Description

This provides a subset of the functionality as the invariant package's Data.Functor.Invariant module, but based on Data.Invertible, without all the instances, and with an interface matching Data.Functor.

This module is intended to be imported qualified, e.g.,:

import qualified Control.Invertible.Functor as Inv
