synopsis:     Concrete functor and monad transformers
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.
