[Haskell-cafe] Type families - how to resolve ambiguities?

Hi, The code below defines a type synonym family: {-# LANGUAGE MultiParamTypeClasses, TypeFamilies #-} {-# LANGUAGE FlexibleInstances, TypeSynonymInstances #-} data Vect k b = V [(b,k)] deriving (Eq,Show) data TensorBasis a b = T a b deriving (Eq, Ord, Show) type family Tensor k u v :: *
