Bug ID: 1798393
Summary: Review Request: ghc-lens-family-core - Haskell 98 Lens
Component: Package Review
QA Contact: extras-qa(a)fedoraproject.org
Target Milestone: ---
Spec URL: https://petersen.fedorapeople.org/reviews//ghc-lens-family-core.spec
This package provides first class(†) functional references. In addition to the
usual operations of getting, setting and composition, plus integration with the
state monad, lens families provide some unique features:
* Polymorphic updating
* Cast projection functions to read-only lenses
* Cast "toList" functions to read-only traversals
* Cast semantic editor combinators to modify-only traversals.
(†) For optimal first-class support use the 'lens-family' package with rank 2 /
rank N polymorphism. "Lens.Family.Clone" allows for first-class support of
lenses and traversals for those who require Haskell 98.
