libghc-monad-control-dev - 1.0.3.1-2+b1 main

It defines the type class MonadControlIO, a subset of MonadIO into
which generic control operations such as catch can be lifted from IO.
Instances are based on monad transformers in MonadTransControl, which
includes all standard monad transformers in the transformers library
except ContT. For convenience, it provides a wrapped version of
Control.Exception with types generalized from IO to all monads in
MonadControlIO.
.
Note that this package is a rewrite of Anders Kaseorg's monad-peel
library. The main difference is that this package provides CPS style
operators and exploits the RankNTypes language extension to simplify
most definitions.
.
The package includes a copy of the monad-peel testsuite written by
Anders Kaseorg. The tests can be performed by using cabal test.
.
The following critertion based benchmark shows that monad-control is
on average about 2.5 times faster than monad-peel:
