There’s a SoC project that was getting Haddock to use GHC as its front end, so that anything GHC understands Haddock will understand.

 I think it’s about 75% complete, but seems to be stalled at the moment.  David W may want to comment?

Subject: Haddock plan -- syntactic extensions?

I'd like to know what's realistic to expect with Haddock and GHC's language extensions in the near future, particularly arrow notation and GADTs.  So far, I've been able to avoid arrow notation, at some cost some obfuscation, but I don't know how to avoid exposing Haddock to my GADTs.
