transformers: Concrete functor and monad transformers
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) and IO monad class (in Control.Monad.IO.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.
