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).

Includes:

• Lenses
• Prisms
• Folds
• Traversals
• Getters
• Reviews
• Setters
• Isos
• Algebraic lenses
• Coalgebraic prisms
• Achromatic lenses
• Grids
• Grates
• Glass
• Loops
• Feedbacks
• Kaleidoscopes

And always growing!
