Readme for proton-0.0.4

[back to package description]

proton - Profunctor optics

An extremely experimental implementation of profunctor optics in Haskell. This mostly exists so I have a place to experiment with new ideas and new optics. Most things should work but I offer no performance guarantees.

Not intended for use in production (yet).
