Re: Parser.y rewrite with parser combinators

I am not against this proposal, but want to raise a possible future concern. As part of improving the haskell tooling environment I am keen on making GHC incremental, and have started a proof of concept based in the same techniques as used in the tree-sitter library. This is achieved by modifying happy, and requires minimal changes to the existing Parser.y. It would be unfortunate if this possibility was prevented by this rewrite. Alan
