-- State monads, passing an updatable state through a computation.
--
-- Some computations may not require the full power of state transformers:
--
-- * For a read-only state, see "Control.Monad.Trans.Reader".
--
-- * To accumulate a value without using it on the way, see
--   "Control.Monad.Trans.Writer".
--
-- This version is lazy; for a strict version, see
-- "Control.Monad.Trans.State.Strict", which has the same interface.
