Readme

This library provides support for a persistent version of the Control.Monad.ST.ST monad. Internally, references are backed by a Data.IntMap.IntMap, rather than being mutable variables on the heap. This decreases performance, but can be useful in certain settings, particularly those involving backtracking.
