./wip/hs-fclabels, First class accessor labels implemented as lenses

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ]

Branch: CURRENT, Version: 1.0.4, Package name: hs-fclabels-1.0.4, Maintainer: pho

First class labels that act as bidirectional record fields.

The labels are implemented as lenses and are fully composable and can
be used to get, set and modify parts of a datatype in a consistent
way. The lens datatype, conveniently called `:->', is an instance of
the Category type class: meaning it has a proper identity and
composition. The library has support for automatically deriving labels
from record selectors that start with an underscore. Labels can be
used in a purely functional setting or be applied to mutable state in
some state monad.
