Just as a note, I never quite understood how we plan to implement #229---is it supposed to be done through state in the lexer, or do we have a simple lexer that keeps all tokens, including white space, and then write a post-processing function to glue and rejigger tokens?

No idea here.

#229 is in fact already implemented: https://gitlab.haskell.org/ghc/ghc/-/merge_requests/1664 I don't remember the details to explain them, but I don't think it turned out hard to implement. Richard
