haskell-MonadCatchIO-transformers: haskell-MonadCatchIO-transformers (functions to deal with exceptions) haskell-MonadCatchIO-transformers: haskell-MonadCatchIO-transformers: Provides functions to throw and catch exceptions. Unlike the haskell-MonadCatchIO-transformers: functions from Control.Exception, which work in IO, these work in haskell-MonadCatchIO-transformers: any stack of monad transformers (from the transformers package) with haskell-MonadCatchIO-transformers: IO as the base monad. You can extend this functionality to other haskell-MonadCatchIO-transformers: monads, by creating an instance of the MonadCatchIO class. Warning: haskell-MonadCatchIO-transformers: this package is deprecated. Use the exceptions package instead, if haskell-MonadCatchIO-transformers: possible. haskell-MonadCatchIO-transformers: haskell-MonadCatchIO-transformers:
