synopsis: Implementation of effect system for Haskell.
description: |
  Implementation of effect system for Haskell (actively maintained fork of
  <http://hackage.haskell.org/package/freer freer>), which is based on the
  work of Oleg Kiselyov et al.:
  .
  * <http://okmij.org/ftp/Haskell/extensible/more.pdf Freer Monads, More Extensible Effects>
  .
  * <http://okmij.org/ftp/Haskell/zseq.pdf Reflection without Remorse>
  .
  * <http://okmij.org/ftp/Haskell/extensible/exteff.pdf Extensible Effects>
  .
  The key features are:
  .
  * An efficient effect system for Haskell - as a library!
  .
  * Reimplementations of several common Haskell monad transformers as effects.
  .
  * Core components for defining your own Effects.
