This package only exports definitions from the "mtl" and "transformers"
Unlike every module of "mtl" it does not reexport
In combination with the "base-prelude" library, this should give you a quite rich prelude.
1.* versions are restricted by
the feature set of
mtl == 2.0.* and
transformers == 0.2.*,
however they provide support for newer versions of those libraries as well.
