persistent-refs-0.4: Haskell references backed by an IntMap for persistence and reversibility.
This library provides support for a persistent version of the
ST
monad. Internally, references are backed by a
IntMap
, rather than being mutable variables on the
heap. This decreases performance, but can be useful in certain
settings, particularly those involving backtracking.
