Provides the graded monad structure to Haskell with a number of analogs of familiar monads (Reader, Writer, State, Maybe, Counter, Update) and a wrapper over normal monads (Control.Effect.Monad). This provides a way to embed effect systems into Haskell. For more information see with paper "Embedding effect systems in Haskell" by Orchard and Petricek http://www.cl.cam.ac.uk/~dao29/publ/haskell14-effects.pdf (Haskell, 2014) and the examples in https://github.com/dorchard/effect-monad/tree/master/examples. (note, this package was previously called ixmonad until September 2014).
