deriving (Eq Foo, Ord Foo)
instead of
deriving (Eq, Ord) for Foo
So what does
newtype Foo a = Foo a
newtype Bar b = Bar b
class C a b
deriving (C (Foo a) (Bar b))
mean? I could see it meaning any or all of the following:
instance (C (Foo a) b) => (C (Foo a) (Bar b))
instance (C a (Bar b)) => (C (Foo a) (Bar b))
instance (C a b) => (C (Foo a) (Bar b))
Perhaps I am misunderstanding?
