I'm pleased to announce the first release of lens-family-core and
lens-family.
This package provide 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 semantic editor combinators to modify-only lenses
(†) 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 for those who require Haskell 98.
