This looks very much fun. A little known fact is that the original Raku implementers were all Haskell heads and PUGS one of the first Raku parsers was written in Haskell by Audrey Tang.

Raku is mainly written in a custom subset “NQP” and the team is now cranking on RakuAST for 6.e which is rewriting the Raku parser as a Raku Grammar.
