Only at separate compilation: Conflicting family instance declarations
Take the following class:
class C a where
type B a
Then the following instances only throw «Conflicting family instance declarations», if compiled separately:
instance C a where
type B a = X a
instance C (Int,a) where
type B (Int,a) = X a
Cheers,
Dorinho
