monad-peel

This package defines MonadPeelIO, a subset of MonadIO into which generic control operations such as catch can be lifted from IO. Instances are based on monad transformers in MonadTransPeel, 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 MonadPeelIO.
