To elaborate a bit on this: the 'use v5' project is pretty much dead at this point in time. (see also my open letter to the Perl community: https://www.perl.com/article/an-open-letter-to-the-perl-community/ https://www.perl.com/article/an-open-letter-to-the-perl-comm... ) To call Perl 5 code from Perl 6, we currently have Inline::Perl5 (https://modules.perl6.org/dist/Inline::Perl5:cpan:NINE https://modules.perl6.org/dist/Inline::Perl5:cpan:NINE): > Supports Perl 5 modules including XS modules. Allows passing integers, strings, arrays, hashes, code references, file handles and objects between Perl 5 and Perl 6. Also supports calling methods on Perl 5 objects from Perl 6 and calling methods on Perl 6 objects from Perl 5 and subclass Perl 5 classes in Perl 6. In a similar vein, there are Inline::Python (https://github.com/niner/Inline-Python/blob/master/README.md https://github.com/niner/Inline-Python/blob/master/README.md) and other Inline modules (https://modules.perl6.org/search/?q=Inline https://modules.perl6.org/search/?q=Inline ) that can be called from Perl 6.
