[Haskell-cafe] unlifted types in classes

Hi all,

I was wondering if it's possible to have a class declaration that would
except both unlifted types and lifted types as instances.


For instance, I'm looking for something like


class Foo a b where

    bar :: a -> b


instance Foo Int Int where

     bar = id


instance Foo Int# Int where

     bar = iBox
