 Why use Perl as there are better alternatives?
 Here, common sense must be applied. I don't believe there is anything like "the perfect" programming language. Everyone has got his preferred (or a set of preferred) programming language to chose from. All programming languages come with their own set of strengths and weaknesses. These are the strengths making Perl shine, and you (technically) don't need to bother to look for "better" alternatives:
 
-Perl is better than Shell/awk/sed scripts. There's a point where shell scripts become fairly complex. The next step-up is to switch to Perl. There are many different versions of shells and awk and sed interpreters. Do you always know which versions (mawk, nawk, gawk, sed, gsed, ...) are currently installed? These commands aren't fully compatible to each other. However, there is only one Perl 5. Simply: Perl is faster, more powerful, more expressive than any shell script can ever be, and it is also extendible through CPAN. Perl can directly talk to databases, which shell scripts can't.

Simply: Perl is faster, more powerful, more expressive than any shell script can ever be, and it is also extendible through CPAN. Perl can directly talk to databases, which shell scripts can't.
 Perl code tends to be compact so that it's much better suitable for "shell scripting" and quick "one-liners" than other languages. In my own experience: Ruby and Python code tends to blow up quickly. It doesn't mean that Ruby and Python are not suitable for this task, but I think Perl does much better.
 Perl 5 has proven itself for decades and is a very stable/robust language. It is a battle-tested and mature as something can ever become.
 Perl is the reference standard for regular expressions. Even so much that there is a PCRE library (Perl Compatible Regular Expressions) used by many other languages now. Perl fully integrates regular expression syntax into the language, which doesn't feel like an odd add-on like in most other languages.

 It's possible to write large programs in Perl (make difficult things possible), but it might not be the best choice here. This also leads back to the clunky object system Perl has. You could write your projects in a procedural or functional style (Perl perfectly fits here), but OOP seems to be the gold standard for large projects nowadays. Functional programming requires a different mindset, and pure procedural programming lacks abstractions.
 Apply common sense. What is the skill set your team has? What's already widely used and supported at work? Which languages comes with the best modules for the things you want to work on? Maybe Python is the answer (better machine learning modules). Maybe Perl is the better choice (better Bioinformatic modules). Perhaps Ruby is already the de-facto standard at work and everyone knows at least a little Ruby (as it happened to be at my workplace) and Ruby is "good enough" for all the tasks already. But that's not a hindrance to throw in a Perl one-liner once in a while :P.

 Why all the sigils? It looks like an exploding ASCII factory!!
-The sigils $ @ % & (where Perl is famously known for) serve a purpose. They seem confusing at first, but they actually make the code better readable. $scalar is a scalar variable (holding a single value), @array is an array (holding a list of values), %hash holds a list of key-value pairs and &sub is for subroutines. A given variable $ref can also hold reference to something. @$arrayref dereferences a reference to an array, %$hashref to a hash, $$scalarref to a scalar, &$subref dereferences a referene to a subroutine, etc. That can be encapsulated as deep as you want. (This paragraph only scratched the surface here of what Perl can do, and there is a lot of syntactic sugar not mentioned here).
-In most other programming languages, you won't know instantly what's the "basic type" of a given variable without looking at the variable declaration or the variable name (If named intelligently, e.g. a variable name containing a list of socks is "sock_list"). Even Ruby makes some use of sigils (@ @@ an $), but that's for a different purpose than in Perl (in Ruby it is about object scope, class scope and global scope). Raku uses all the sigils Perl uses plus an additional bunch of twigils, e.g. $.foo for a scalar object variable with public accessors, $!foo for a private scalar object variable, @.foo, @!foo, %.foo, %!foo and so on. Sigils (and twigils) are very convenient once you get used to them. Don't let them scare you off - they are there to help you!

-Published by Paul at 2021-07-04
+Published by Paul at 2021-07-04 12:51:23 GMT
 When I was a Linux System Administrator, I have been programming in Perl for years. I still maintain some personal Perl programming projects (e.g. Xerl, guprecords, Loadbars). After switching jobs a couple of years ago (becoming a Site Reliability Engineer), I found Ruby (and some Python) widely used there. As I wanted to do something new, I decided to give Ruby a go.
 You should learn or try out one new programming language once yearly anyway. If you end up not using the new language, that's not a problem. You will learn new techniques with each new programming language and this also helps you to improve your overall programming skills even for other languages. Also, having some background in a similar programming language makes it reasonably easy to get started. Besides that, learning a new programming language is kick-a** fun!

 I am currently looking into the functional programming language Standard ML (aka SML). The purpose is to refresh my functional programming skills and to learn something new too. Since I already knew a little Haskell, I could not help myself, and I also implemented the same exercises in Haskell.
 As you will see, SML and Haskell are very similar (at least when it comes to the basics). However, the syntax of Haskell is a bit more "advanced". Haskell utilizes fewer keywords (e.g. no val, end, fun, fn ...). Haskell also allows to write down the function types explicitly. What I have been missing in SML so far is the so-called pattern guards. Although this is a very superficial comparison for now, so far, I like Haskell more than SML. Nevertheless, I thought it would be fun to demonstrate a few simple functions of both languages to show off the similarities. 
 Haskell is also a "pure functional" programming language, whereas SML also makes explicit use of imperative concepts. I am by far not a specialist in either of these languages, but here are a few functions implemented in both SML and Haskell:

-I tried Doom Emacs, but I switched back to (Neo)Vim
-As a long-lasting user of Vim (and NeoVim), I always wondered what the fuzz about Emacs is about! So I decided to give Emacs a try. I tried out Emacs, but Doom Emacs and not vanilla Emacs. I chose Doom Emacs as it is a pretty neat distribution of Emacs with Evil mode enabled by default. Evil mode allows Vi(m) key bindings, and I am pretty sure I won't be ready to give up all the Vi muscle memory I have built over more than ten years.
-I used Doom Emacs for around two months, but ultimately I decided to switch back to NeoVim as my primary editor and IDE and Vim as my "always available editor" for quick edits. So why is that?
-Emacs is a monster
-Emacs feels like a monster as it is much more than an editor or an integrated development environment. Emacs is a whole platform on its own. There's an E-Mail client, an IRC client, or even games you can run within Emacs. And you can also change Emacs within Emacs using its own Lisp dialect, Emacs Lisp. Therefore, Emacs is also its own programming language... You can change every aspect of Emacs within Emacs. People jokingly state Emacs is an operating system and that you should directly boot into Emacs as the init 1 process!
-In many aspects, Emacs is like shooting at everything with a rail gun! However, I prefer it simple. I only wanted Emacs to be a good editor (which it is, too), but there's too much other stuff in Emacs that I, frankly, don't care about! Vim and NeoVim do one thing excellent: Being great text editors and, when loaded with plugins, a decent IDEs, too. Yes, VimScript, to program the editor, feels clunky and is by far not as elegant as Emacs Lisp, but it gets its job done! NeoVim is also programmable with Lua, which seems to be a step up. 
-Magit love
-I almost fell in love with Magit, a fully integrated Git client for Emacs. But I think the best way to interact with Git is to use the git command line directly. I don't worry about typing out all the commands, as the most commonly used commands are in my shell history. Other useful Git programs I use frequently are bit and tig. 
-Magit is pretty neat for basic Git operations, but I found myself searching the internet for the correct sub-commands to do the things I wanted to do in Git. Mainly I found the way how branches are managed confusing. Often, I fell back to the command line to fix up the mess I produced with Magit (e.g. accidentally pushing to the wrong remote branch).
-Seeking simplicity
-I am not ready to dive deep into the whole world of Emacs. I prefer small and simple tools as opposed to complex tools. Emacs comes with many features out of the box, whereas in Vim/NeoVim, you would need to install many plugins to replicate the behaviour. Yes, I need to invest time managing all the Vim/NeoVim plugins I use, but I feel more in control compared to Doom Emacs, where a framework around vanilla Emacs manages all the plugins. I could use vanilla Emacs and manage all my plugins the vanilla way, but for me, it's not worth the effort to learn and dive into that as all that I want to do I can already do with Vim/NeoVim.
-I am not saying that Vim/NeoVim are simple programs, but they are much simpler than Emacs with much smaller footprints; furthermore, they appear to be more straightforward as I am used to them. I only need Vim/NeoVim to be an editor, an IDE (through some plugins), and nothing more.
-Scripting it
-It is possible to customize every aspect of Emacs through Emacs Lisp. I have done some Elk Scheme programming in the past (a dialect of Lisp), but that was a long time ago, and I am not willing to dive here again to customize my environment. I would rather take the pragmatic approach and script what I need in VimScript (a terrible language, but it gets the job done!). I watched Damian Conway's VimScript course on O'Reilly Safari Books Online, which I greatly recommend.
-Scripting Vim by Damian Conway

-One example is my workflow of how I write blog articles. I am writing everything in NeoVim, but I also want to have every paragraph checked against Grammarly (as English is not my first language). So I write a whole paragraph, then I select the entire paragraph via visual selection with SHIFT+v, and then I press ,y to yank the paragraph to the systems clipboard, then I paste the paragraph to Grammarly's browser window, let Grammarly suggest the improvements, and then I copy the result back to the system clipboard and in NeoVim I type ,i to insert the result back overriding the old paragraph with the new content. That all sounds a bit complicated, but it's surprisingly natural and efficient.
-For the clipboard integration, I use this small VimScript snippet, and I didn't have to dig into any Lisp for this:
--" Clipboard
-
-if uname != 'Darwin'
-  vnoremap ,y !gpaste-client<CR>ugv
-  vnoremap ,i !gpaste-client --use-index get 0<CR>
-  nmap ,i !wgpaste-client --use-index get 0<CR>
-else
-  vnoremap ,y !pbcopy<CR>ugv
-  vnoremap ,i !pbpaste<CR>
-  nmap ,i !wpbpaste<CR>
-endif
-


-The famous Org mode
-Org mode: Ranger
-Conclusion
-I believe I started to understand the Emacs users now. Emacs is a incredible powerful platform for almost everything not just for text editing. If you want to have one piece of software which rules it all and you are happy to invest a large part of your time in your platform: Pick Emacs and over time Emacs will become "your" Emacs, customized to your own needs which makes the Emacs users stick even more to it. With Emacs you can do nearly everything (Editing, programming, calendar scheduling and note taking, Jira integration, play games, read/write emails, browse the web, use as a calculator, generate HTML pages, configure interactive menus, jump around between every feature and every file within one single session, chat on IRC, surf the Gotherspace, ... the options are endless....).
-Vim/NeoVim comes also with a very high degree of customization options, but to a lesser extreme than Emacs. If you want to have the best editor of the world, which can also be tweaked to be a decent IDE, and that's you are only looking for: Pick Vim or NeoVim! You would also need to invest a lot of time in learning, tweaking and customizing Vim/NeoVim, but I think that's a little bit more straightforward and the end-result is much more lightweight.

 Here are some reasons why not to chose Perl and look for "better" alternatives:
 
-If performance is your main objectives, then Perl might not be the language to use. Perl is a dynamic interpreted language, and it will generally never be as fast as statically typed languages compiled to native binaries (e.g. C/C++/Rust/Haskell) or statically typed languages run in a VM with JIT (e.g. Java) or gradually typed languages run in a VM (e.g. Raku) or languages like Golang (statically typed, compiled to a binary but still with a runtime in the binary). Perl might be still faster than the other language listed here in certain circumstances (e.g. faster startup time than Java), but usually it's not. It's not a problem of Perl, it's a problem of all dynamic scripting languages including Python, Ruby, ....

It's not a problem of Perl, it's a problem of all dynamic scripting languages including Python, Ruby, ....
 Don't use Perl (just yet) if you want to code object-oriented. Perl supports OOP, but it feels clunky and odd to use (blessed references to any data types are objects) and doesn't support real encapsulation out of the box. There are many (many) extensions available on CPAN to make OOP better, but that's totally fragmented. The most popular extension, Moose, comes with a huge dependency tree. But wait for Perl 7. It will maybe come with a new object system (an object system inspired by Raku).
 It's possible to write large programs in Perl (make difficult things possible), but it might not be the best choice here. This also leads back to the clunky object system Perl has. You could write your projects in a procedural or functional style (Perl perfectly fits here), but OOP seems to be the gold standard for large projects nowadays. Functional programming requires a different mindset, and pure procedural programming lacks abstractions.
 Apply common sense. What is the skill set your team has? What's already widely used and supported at work? Which languages comes with the best modules for the things you want to work on? Maybe Python is the answer (better machine learning modules). Maybe Perl is the better choice (better Bioinformatic modules). Perhaps Ruby is already the de-facto standard at work and everyone knows at least a little Ruby (as it happened to be at my workplace) and Ruby is "good enough" for all the tasks already. But that's not a hindrance to throw in a Perl one-liner once in a while :P.

 Here are some reasons why not to chose Perl and look for "better" alternatives:
 
-If performance is your main objectives, then Perl might not be the language to use. Perl is a dynamic interpreted language, and it will generally never be as fast as statically typed languages compiled to native binaries (e.g. C/C++/Rust/Haskell) or statically typed languages run in a VM with JIT (e.g. Java) or gradually typed languages run in a VM (e.g. Raku) or languages like Golang (statically typed, compiled to a binary but still with a runtime in the binary). Perl might be still faster than the other language listed here in certain circumstances (e.g. faster startup time than Java), but usually it's not. It's not a problem of Perl, it's a problem of all dynamic scripting languages including Python, Ruby, ....

It's not a problem of Perl, it's a problem of all dynamic scripting languages including Python, Ruby, ....
 Don't use Perl (just yet) if you want to code object-oriented. Perl supports OOP, but it feels clunky and odd to use (blessed references to any data types are objects) and doesn't support real encapsulation out of the box. There are many (many) extensions available on CPAN to make OOP better, but that's totally fragmented. The most popular extension, Moose, comes with a huge dependency tree. But wait for Perl 7. It will maybe come with a new object system (an object system inspired by Raku).
 It's possible to write large programs in Perl (make difficult things possible), but it might not be the best choice here. This also leads back to the clunky object system Perl has. You could write your projects in a procedural or functional style (Perl perfectly fits here), but OOP seems to be the gold standard for large projects nowadays. Functional programming requires a different mindset, and pure procedural programming lacks abstractions.
 Apply common sense. What is the skill set your team has? What's already widely used and supported at work? Which languages comes with the best modules for the things you want to work on? Maybe Python is the answer (better machine learning modules). Maybe Perl is the better choice (better Bioinformatic modules). Perhaps Ruby is already the de-facto standard at work and everyone knows at least a little Ruby (as it happened to be at my workplace) and Ruby is "good enough" for all the tasks already. But that's not a hindrance to throw in a Perl one-liner once in a while :P.

 Why all the sigils? It looks like an exploding ASCII factory!!
-The sigils $ @ % & (where Perl is famously known for) serve a purpose.

 In most other programming languages, you won't know instantly what's the "basic type" of a given variable without looking at the variable declaration or the variable name (If named intelligently, e.g. a variable name containing a list of socks is "sock_list"). Even Ruby makes some use of sigils (@, @@ and $), but that's for a different purpose than in Perl (in Ruby it is about object scope, class scope and global scope). Raku uses all the sigils Perl uses plus an additional bunch of twigils, e.g. $.foo for a scalar object variable with public accessors, $!foo for a private scalar object variable, @.foo, @!foo, %.foo, %!foo and so on. Sigils (and twigils) are very convenient once you get used to them. Don't let them scare you off - they are there to help you!

 You should learn or try out one new programming language once yearly anyway. If you end up not using the new language, that's not a problem. You will learn new techniques with each new programming language and this also helps you to improve your overall programming skills even for other languages. Also, having some background in a similar programming language makes it reasonably easy to get started. Besides that, learning a new programming language is kick-a** fun!

 I am currently looking into the functional programming language Standard ML (aka SML). The purpose is to refresh my functional programming skills and to learn something new too. Since I already knew a little Haskell, I could not help myself, and I also implemented the same exercises in Haskell.
 As you will see, SML and Haskell are very similar (at least when it comes to the basics). However, the syntax of Haskell is a bit more "advanced". Haskell utilizes fewer keywords (e.g. no val, end, fun, fn ...). Haskell also allows to write down the function types explicitly. What I have been missing in SML so far is the so-called pattern guards. Although this is a very superficial comparison for now, so far, I like Haskell more than SML. Nevertheless, I thought it would be fun to demonstrate a few simple functions of both languages to show off the similarities.

 You should learn or try out one new programming language once yearly anyway. If you end up not using the new language, that's not a problem. You will learn new techniques with each new programming language and this also helps you to improve your overall programming skills even for other languages. Also, having some background in a similar programming language makes it reasonably easy to get started. Besides that, learning a new programming language is kick-a** fun!

 In computing, a polyglot is a computer program or script written in a valid form of multiple programming languages, which performs the same operations or output independent of the programming language used to compile or interpret it.

 I am currently looking into the functional programming language Standard ML (aka SML). The purpose is to refresh my functional programming skills and to learn something new too. Since I already knew a little Haskell, I could not help myself, and I also implemented the same exercises in Haskell.
 As you will see, SML and Haskell are very similar (at least when it comes to the basics). However, the syntax of Haskell is a bit more "advanced". Haskell utilizes fewer keywords (e.g. no val, end, fun, fn ...). Haskell also allows to write down the function types explicitly. What I have been missing in SML so far is the so-called pattern guards. Although this is a very superficial comparison for now, so far, I like Haskell more than SML. Nevertheless, I thought it would be fun to demonstrate a few simple functions of both languages to show off the similarities.
