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@: + + <https://github.com/basvandijk/bench-monad-peel-control> + </longdescription> + <use> + <flag name="instancest"> + If enabled this package will export + MonadBaseControl instances for the lazy and strict ST monad.
