From the perspective of somebody who needs a production-grade Perl implementation, Rakudo doesn't cut it, I'm saddened to say.

Monthly releases are a good step in the right direction, but they aren't very useful to those of us who need something more robust.

Perl 5 currently offers this robustness, while Rakudo unfortunately does not. The other Perl 6 implementations end up being worse than Rakudo in this respect, as well.
