Summary: GHCi :i ommits constraints
Initial Comment:
hello,
GHCi ommits the constraints on a data constructor when using
the ":i" command:
> class C a
> newtype C a => T a = T a
*Main> :i T
-- T is a data constructor, defined at bug2.lhs:4
T :: forall a. a -> T a (*** C a is missing ***)
-- T is a type constructor, defined at bug2.lhs:4
newtype (C a) => T a = T a
*Main> :t T
forall a. (C a) => a -> T a
bye
