I'm not really able to follow the details of this, but I wanted to raise to everyone's attention a serious bug with the current GHC 7.10 RC, Cabal 1.22, and/or Haddock. Currently, running `cabal haddock --hoogle` does not work. There seem to be two different issues open about it:
https://github.com/haskell/haddock/issues/361 https://github.com/haskell/cabal/issues/2297
I really don't understand the issues here, but I'd claim that the severity of this should probably be a blocker for a GHC 7.10 release.
There may be more to this issue that I am seeing at the moment but I believe I have a fix here [1]. There's also a patch improving the error handling in Haddock here [2]. Cheers, - Ben [1] https://github.com/haskell/cabal/pull/2439 [2] https://github.com/haskell/haddock/pull/369
