This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.
The I/O monad transformer, PlusMonad, and Linear modules are deprecated. Their use is discouraged. This package is now about automatic monad lifting; and includes a rigorous implementation of Luth and Ghani coproducts structured around the Free monad.
