The `freer-simple` library is an implementation of an *extensible effect system* for Haskell, a general-purpose way of tracking effects at the type level and handling them in different ways. The concept of an “effect” is very general: it encompasses the things most people consider side-effects, like generating random values, interacting with the file system, and mutating state, but it also includes things like access to an immutable global environment and exception handling.

- A combinator language for defining your own effects, designed to make simple, common use cases easy to read and write.

## Acknowledgements
The `freer-simple` package began as a fork of [freer-effects](http://hackage.haskell.org/package/freer-effects) by Ixperta Solutions, which in turn is a fork of [freer](http://hackage.haskell.org/package/freer) by Allele Dev. All implementations are based on the [paper and reference implementation by Oleg Kiselyov](http://okmij.org/ftp/Haskell/extensible/more.pdf).
