-Perl5.pm for rakudo
-
 Currently Perl5.pm will only be imported if you do 'use Perl5'. In near future this module will be picked up
 for statements like 'use v5;' and 'use 5.10'.
 This module is not installable via panda yet, and can only be used if your Cwd is the repo's root directory
 and if you set PERL6LIB to 'blib'.
