This Haskell library provides an implementation of the MonadPlus type class that enumerates results of a non-deterministic computation by interleaving subcomputations in a way that has usually much better memory performance than other strategies with the same termination properties.
By using supensions in strategic positions, the user can ensure that the search does not diverge if there are remaining non-deterministic results.
