Module documentation for 0.4

Control
- Control.Monad
  - Control.Monad.ST
    - Control.Monad.ST.Persistent
Data
- Data.STRef
  - Data.STRef.Persistent

Depends on 5 packages(full list with versions):

base, containers, mtl, ref-fd, transformers

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.
