Replying just to you to avoid spamming everyone.
Hmm, you did write to the list as well...
[...]
I don't agree. What do you mean by "distinct types"? In H98 both of these are ok:
f :: CD a => ty f = ...code...
g :: (C a, D a) => ty g = f
This is not okay. Hugs gives this error message (with ty = a):
Cannot justify constraints in explicitly typed binding *** Expression : g *** Type : (C a, D a) => a *** Given context : (C a, D a) *** Constraints : CD a
[...]
