Following the announcement of lens-family, I'm pleased to announce lens-family-th 0.1.0.0, a Template Haskell library supplying macros to generate lens-family lenses for fields of data types declared with record syntax.
Be warned that currently, type signatures are *not* generated alongside the lens definitions. Type inference should correctly determine the type of the generated lenses, but I have structured the library code so that in the future, type signatures can also be generated. Patches welcome! http://hackage.haskell.org/package/lens-family-th -- Dan Burton
