libghc-monadcatchio-transformers-dev 0.3.0.0-5 (i386 binary) in ubuntu trusty

 Provides functions to throw and catch exceptions. Unlike the functions from
 Control.Exception, which work in IO, these work in any stack of monad
 transformers (from the 'transformers' package) with IO as the base monad.
 You can extend this functionality to other monads, by creating an instance
 of the MonadCatchIO class.
 This package provides a library for the Haskell programming language.
 See http://www.haskell.org/ for more information on Haskell.
