Monatron

Monad transformer library with uniform liftings.

An extensible monad transformer library with uniform liftings, a fairly portable core, and option of explicit naming of liftings. See http://www.fceia.unr.edu.ar/~mjj/Monatron/ for more information. The monad zipper allows modular composition of components with Monatron effects. It is a contribution of Bruno Oliveira and Tom Schrijvers.
