Perl is my preference of the three (Perl, Python, Ruby). I agree with 'There Is More Than One Way To Do It', and disagree with 'There Is Only One Way To Do It'. And Perl has the best support for regular expressions. Ruby is OK, but I learned Perl first, so it feels more natural.
To me this sounds a bit like driving to a supermarket three towns away because it has the best selection of coffee filters... :)
But sometimes there is a builtin module that makes something easier to do, so I am faced with a 'Kobayashi Maru', a no-win situation
I've never used Nim or Crystal. Rust is too complicated for me to bootstrap and not particularly compatible with older architectures as far as I remember (I believe had trouble with compiling 32-bit)

While `from modA import nil` does exist, it is not very idiomatic. Idiomatic is more managing the global namespace with the type system/overload resolution which it sounds like you would hate. However, shadowing outer scope names with inner scope names (like your `str` example) *is* considered idiomatic.
