How To Install ghc-monad-control on CentOS 7
Introduction
In this tutorial we learn how to install ghc-monad-control on CentOS 7.
What is ghc-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. 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. A criterion-based benchmark shows that monad-control is on average about 99% faster than monad-peel.
