[Haskell-cafe] "Cofunctor" as a name

I've heard contravariant functors referred to as "cofunctors", and I've also heard objections to that term. As I'm preparing to release some libraries using contravariant functors, I'd appreciate hearing preferences and/or reasons. For instance, another name would be "Contrafunctor". -- | Contravariant functors. often useful for /acceptors/ (consumers, -- sinks) of values. class Cofunctor acc where cofmap :: (a -> b) -> (acc b -> acc a) Thanks, - Conal
