Optics.Each.Core

This module defines the Each class, which provides an IxTraversal that extracts each element of a (potentially monomorphic) container.

Note that orphan instances for this class are defined in the Optics.Each module from optics-extra, so if you are not simply depending on optics you may wish to import that module instead.
