What version of GHC are you using? This works in 6.6:
{-# LANGUAGE MultiParamTypeClasses,
OverlappingInstances #-}
module Q where
class Foo a b where
foo :: a -> b
instance Foo Int Bool
instance Foo Int a
x :: Int -> Bool
x = foo

This also works:
{-# LANGUAGE MultiParamTypeClasses #-}
{-# LANGUAGE OverlappingInstances #-}
module Q where
class Foo a b where
foo :: a -> b
instance Foo Int Bool
instance Foo Int a
x :: Int -> Bool
x = foo
Thanks
Ian
