optics: Optics as an abstract interface

[ bsd3, data, lenses, library, optics ] [ Propose Tags ]

This package makes it possible to define and use Lenses, Traversals, Prisms and other optics, using an abstract interface. See the main module Optics for the documentation.

This is the "batteries-included" variant with many dependencies; see the optics-core package and other optics-* dependencies if you need a more limited dependency footprint.
