This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.

Provides the graded monad structure to Haskell via Control.Effect
with a number of analogs of familiar monads and some new things:
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 the paper
"Embedding effect systems in Haskell" by Orchard and Petricek
http://dorchard.co.uk/publ/haskell14-effects.pdf (Haskell, 2014)
Also provides the parameterised monad structure due to Atkey in
Control.Effect.Parameterised along with some instances:
AtomicState, SafeFiles, ExtensibleState
and the examples in https://github.com/dorchard/effect-monad/tree/master/examples.
(note, this package was previously called ixmonad until September 2014).
