Crate operational [−] [src]

The operational library makes it easy to implement monads with tricky control flow.

This is very useful for: writing web applications in a sequential style, programming games with a uniform interface for human and AI players and easy replay, implementing fast parser monads, designing monadic DSLs, etc.

A thorough introduction to the ideas behind this library is given in "The Operational Monad Tutorial", published in Issue 15 of the Monad.Reader.
