I'm using haskell-src, and I noticed that the data types defined in Language.Haskell.Syntax don't derive Ord. It makes sense, cause there's no logical way to ordenate them, but it makes it impossible to use with Data.Set functions, such as fromList. It would be good to be possible to use Data.Set with these types, so maybe including deriving Ord to the data types is a good idea.
I've made a patch to haskell-src 1.0.1.2 that makes all types instance of Ord.
