DeepControl.Monad

This module enables you to program in Monad for more deeper level than the usual Monad module expresses. You would soon realize exactly what more deeper level means by reading the example codes in order, which are attached on the Monadx(Monad2, Monad3, etc) classes below.

Note:

• This module never makes mlt(monad-transformer-library) unnessasary. The range in which this module is helpful is regrettably confined to the range of deep monads (namely Monad2, Monad3, etc).
• In my opinion this bad confinement is hard-wired with the ability of the compiler, that is to say GHC doesn't parse (r->) or ((->) r) as a data constructor; thus some fundamental expressions such as (r->)|$> or fmap (r->) are useless. Theoretically it might be impossible though.
