I am (still) working on !2418 to bring the API Annotations into the GHC ParsedSource, and making good progress.
I am currently making a rough port of ghc-exactprint, to ensure I can get all the tests around modifying the AST to work. One of the last pieces is being able to capture the spacing from the last token in the file to the EOF. I guess technically it is the second last token. Empirically (calling getTokenStream), it seems this is always ITsemi. I am not sure how this comes about, as the `module` parsing rule in Parser.y ends with body or body2, and those both finish with an actual or virtual '}'. Can I rely on the token before ITEof always being ITsemi? Alan
