The devel/hs-lens port

hs-lens-3.7.6 – lenses, folds and traversals

Description

This package comes "Batteries Included" with many useful lenses
for the types commonly used from the Haskell Platform, and with
tools for automatically generating lenses and isomorphisms for
user-supplied data types.
The combinators in Control.Lens provide a highly generic toolbox
for composing families of getters, folds, isomorphisms, traversals,
setters and lenses and their indexed variants.
