* [Haskell wikibook: Understanding monads](http://en.wikibooks.org/wiki/Haskell/Understanding_monads)
The first section is an extended example of the use of monads. A simple interpreter is modified to support various extra features: error messages, state, output, and non-deterministic choice. The second section describes the relation between monads and continuation-passing style. The third section sketches how monads are used in a compiler for Haskell that is written in Haskell.
