Pugs

Perl Users' Golfing System

Pugs originally started as an implementation of Perl 6 on Haskell.

It has since grown to include libraries that make Perl 6 features available under Perl 5 (via CPAN).

Pugs is working on making Perl 6 available on multiple runtime platforms, including Haskell (GHC), Perl 5, JavaScript, and Parrot.
