Perl is now my favorite scripting language, at the moment I mainly use Perl5 but I'm impatiently waiting to use Raku (formally known as Perl6), (well I'm trailing the rakudo implementation of Perl6 very cool).

I have also been trailing the niecza implementation of Perl6 very nice. I've tried some of the others but haven't succeeded with Pugs yet.

OK update there is only the rakudo implementation now, and the language is now called raku, and I am using it more and more now.
