| Description: | A portable library of functor and monad transformers, inspired by the paper
"Functional Programming with Overloading and Higher-Order Polymorphism", by
Mark P Jones, in "Advanced School of Functional Programming", 1995
(<http://web.cecs.pdx.edu/~mpj/pubs/springschool.html>).
This package contains:
* the monad transformer class (in "Control.Monad.Trans.Class")
* concrete functor and monad transformers, each with associated operations and
functions to lift operations associated with other transformers.
It can be used on its own in portable Haskell code, or with the monad classes
in the 'mtl' or 'monads-tf' packages, which automatically lift operations
introduced by monad transformers through other transformers. |
