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.
Control.Effects is a library for programming with effects, like in the the Eff language by Andrej Bauer and Matija Pretnar. Effects can be used instead of monad transformers.
See the home page for some example code.
