Gentoo Haskell
Monad classes using type families, with instances for various
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 is almost a compatible replacement for the @mtl-tf@ package.
