Hmm, it seems only partial: documentation attached to an instance is shown in the list of instances under a type, but not the list under a class.

I'm guessing that's to reduce noise...

I'm guessing it might have something to do with the fact that often the module containing the class definition isn't processed together with the module containing the instance declaration.

Actually Haddock attaches instance information to the modules in a separate step after having processed all of them. The fact that no documentation shows up for instances under the class documentation is a bug, embarrasingly enough, which I hadn't noticed. Looking at the code, it's not that I've forgotten to add code to the Html backend, it's something deeper that is wrong, so I will have to investigate.

I found the bug and fixed it, it's in the latest darcs version at http://code.haskell.org/haddock. David
