mapMState :: (MonadIO m, MonadIO n) => (m (a, t) -> n (b, t)) -> MState t m a -> MState t n bmstate Control.Concurrent.MState Map a stateful computation from one (return value, state) pair to another. See Control.Monad.State.Lazy for more information. Be aware that both MStates still share the same state.
