abstract class Yoneda[F[_], A] extends Serializable

The cofree functor for F. The Yoneda lemma says that Yoneda[F,A] is isomorphic to F[A] for any functor F. The function from Yoneda[F, A] to F[A] exists even when we have forgotten that F is a functor. Can be seen as a partially applied map for the functor F.
