Description:
implementation of difficult monads made easy with operational semantics; profiling libraries
This library makes it easy to implement monads with tricky control flow. . This is useful for: writing web applications in a sequential style, programming games with a uniform interface for human and AI players and easy replay capababilities, implementing fast parser monads, designing monadic DSLs, etc. . This package provides a library for the Haskell programming language, compiled for profiling. See http://www.haskell.org/ for more information on Haskell.
