Corepresentable functors as vector spaces

Documentation

class Functor f => Core f where

A Functor f is corepresentable if it is isomorphic to (x -> a) for some x. Nearly all such functors can be represented by choosing x to be the set of lenses that are polymorphic in the contents of the Functor, that is to say x = Rep f is a valid choice of x for (nearly) every Representable Functor.
