[back to package description]representable-functors
This package provides representable functors for haskell. In category theory a representable functor (more pedantically a corepresentable functor) is one such that f a is isomorphic to x -> a. We choose the name Representable here because we are talking about haskell Functor instances, and they are all covariant, so this is the more natural notion of representability for Haskell.
