Accumulate Haddock comments in P (#17544, #17561, #8944)wip/haddock-accum
Haddock comments are, first and foremost, comments. It's very annoying to incorporate them into the grammar. We can take advantage of an important property: adding a Haddock comment does not change the parse tree in any way other than wrapping some nodes in HsDocTy and the like (and if it does, that's a bug). This patch implements the following: * Accumulate Haddock comments with their locations in the P monad. This is handled in the lexer. * After parsing, do a pass over the AST to associate Haddock comments with AST nodes using location info. * Report the leftover comments to the user as a warning (-Winvalid-haddock).
