I'm headed to Frozen Perl tomorrow. My talk is titled Using Rakudo Grammars, but it ended up being more about Perl 6 than specifically the Parrot/Rakudo implementation.
I'm looking forward to the hackathon Sunday. I'm thinking that I'd like to work on enabling any language's PCT actions.pm to be implemented in Rakudo instead of NQP. Patrick Michaud mentioned a few blockers in IRC, so I'm hoping to work on those.
