Thanks - I'm glad it's not just me! In the meantime, I found a better workaround (since the type decl using a class name is not legal Haskell) is just to use -cpp to preprocess for both ghc and haddock so that haddock sees explicitly defined dummy instances instead of a newtype deriving clause, then perfect results are obtained...
This workaround is actually "state-of-the-art"! :-P If you look at the hierarchical libraries, there is often code like: data VertexArrayDescriptor a = VertexArrayDescriptor !NumComponents !DataType !Stride !(Ptr a) #ifdef __HADDOCK__ -- Help Haddock a bit, because it doesn't do any instance inference. instance Eq (VertexArrayDescriptor a) instance Ord (VertexArrayDescriptor a) instance Show (VertexArrayDescriptor a) #else deriving ( Eq, Ord, Show ) #endif Cheers, S.
