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.

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.
