monad-control

This package defines the type class MonadBaseControl, a subset of MonadBase into which generic control operations such as catch can be lifted from IO or any other base monad. Instances are based on monad transformers in MonadTransControl, which includes all standard monad transformers in the transformers library except ContT. See the lifted-base package which uses monad-control to lift IO operations from the base library (like catch or bracket) into any monad that is an instance of MonadBase or MonadBaseControl. 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 and TypeFamilies language extensions to simplify and speedup most definitions.

Hackage Build Status

This package 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.

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.

This criterion based benchmark shows that monad-control is on average about 2.5 times faster than monad-peel.
