I want to encourage people to hack on this. Although you have to work around many missing features and some bugs in Rakudo it's quite fun to work with it. Especially hacking on the grammar (for the wiki markup and for the HTML::Template in Perl 6) was quite fun, and the patches get applied really fast.

Hacking on a real application reveals quite different bugs than those that the test suite knows about: The test suite is mostly about typical behaviour and edge cases, but not about real-world complexity.

(A mostly off-topic note which might also fit into Perl News: about a week ago I started a Blog series about Perl 6, a mixture of a tutorial, a feature show-off and some thoughts on language design)
