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.
    .
    The package can be used on its own in portable Haskell code, in
    which case operations need to be manually lifted through transformer
    stacks (see "Control.Monad.Trans.Class" for some examples).
    Alternatively, it can be used with the non-portable monad classes in
    the @mtl@ or @monads-tf@ packages, which automatically lift operations
    introduced by monad transformers through other transformers.
