Synopsis:      First class accessor labels implemented as lenses.
Description:   This package provides first class labels that can act as
               bidirectional record fields. The labels can be derived
               automatically using Template Haskell which means you don't have
               to write any boilerplate yourself. The labels are implemented as
               /lenses/ and are fully composable. Lenses can be used to /get/,
               /set/ and /modify/ parts of a data type in a consistent way.
               .
               See "Data.Label" for an introductory explanation or see the
               introductory blog post at
               <http://fvisser.nl/post/2013/okt/1/fclabels-2.0.html>
               .
               * /Total and partial lenses/
               .
               Internally lenses do not used Haskell functions directly, but
               are implemented as categories. Categories allow the lenses to be
               run in custom computational contexts. This approach allows us to
               make partial lenses that point to fields of multi-constructor
               datatypes in an elegant way.
               .
               See "Data.Label.Partial" for the use of partial labels.
               .
               * /Monomorphic and polymorphic lenses/
               .
               We have both polymorphic and monomorphic lenses. Polymorphic
               lenses allow updates that change the type. The types of
               polymorphic lenses are slightly more verbose than their
               monomorphic counterparts, but their usage is similar. Because
               monomorphic lenses are built by restricting the types of
               polymorphic lenses they are essentially the same and can be
               freely composed with eachother.
               .
               See "Data.Label.Mono" and "Data.Label.Poly" for the difference
               between polymorphic and monomorphic lenses.
               .
               * /Using fclabels/
               .
               To simplify working with labels we supply both a set of labels
               for Haskell's base types, like lists, tuples, Maybe and Either,
               and we supply a set of combinators for working with labels for
               values in the Reader and State monad.
               .
               See "Data.Label.Base" and "Data.Label.Monadic" for more
               information.
               .
