The MTL provides a selection of monads and their transformer variants along with type classes that allow uniform handling of a base monad and its transformer.

See the package on Hackage.

Version 2 of the MTL has some small incompatibilities with version 1. See this page for instructions on how to make code written for version 1 work with version 2.
