I also make use of the "assign-then-shift"-pattern which goes like this: "local -r var1=$1; shift; local -r var2=$1; shift". The idea is that you only use "$1" to assign function arguments to better readable function arguments and never have to bother about "$2" or above. It is very useful when you constantly refactor your code and remove or add function arguments. It's something what I picked up from a colleague (a purely Bash wizard) some time ago.
