Rakudo Star Offers a Useful and Usable Perl 6 Distribution
Perl 6 isn't done yet, but for early adopters out there, Rakudo Star is available for tinkering.
"We know that it still has some bugs," Rakudo's announcement explains, "it is far slower than it ought to be, and there are some advanced pieces of the Perl 6 language specification that aren't implemented yet. But Rakudo Perl 6 in its current form is also proving to be viable (and fun) for developing applications and exploring a great new language."
