This is 'Niecza', which will eventually be a Perl 6 implementation focusing on optimization research. It targets the Common Language Runtime (ECMA-335; implementations are "Mono" and ".NET").

To see the current state of the art, the best documentation is the testsuite, test.pl.

• Mono. 2.6.4 and later are well-tested, though success has been reported with 2.4.x as well. ggoebel on #perl6 reports that 2.6.7 fails with a bus error on OS X 10.4 x86, but 2.6.4 works; 2.6.7 is fine on other platforms.

  Debian and derivatives have a modular mono packaging; you should install 'mono-complete'. (The other packages exist for the sake of Debian-packaged programs.)

• Perl 5.10.1 (or 5.10.0 with autodie installed from CPAN) in your PATH

• Moose, Sub::Exporter, File::Slurp, Term::ReadLine, IPC::System::Simple, JSON, STD, File::ShareDir, and YAML::XS from CPAN
