The compose-trans package

[ Tags: bsd3, library, monads ] [ Propose Tags ]

A version of monad transformers that (a) allows one to convince the type checker that transformer application is a monad, and (b) doesn't need lots of boilerplate to add a new transformer. It's supposed to play nicely with Control.Monad.Trans.

In order to make a new transformer (say, T) an instance of TransM (TransP, TransF) class, all you have to do is:

After that, you can use your new and shiny transformer in compositions, like ReaderT Char :. T :. WriterT String — and such a composition would automagically become a monad transmormer.
