- Mismatched contexts
- When matching the contexts of the signatures for `g' and `f'
- (the signature contexts in a mutually recursive group should all be identical)
-
-tcfail071.hs:10:
- Cannot unify the type-signature variable `c'
- with the type `a -> b -> b'
- Expected type: a -> b -> b
- Inferred type: c
- In the first argument of `f', namely `c'
- In the first argument of `foldr', namely `(f c)'
