monad-task: A monad transformer that turns event processing into co-routine programming.

[ bsd3, control, library ] [ Propose Tags ]

Task monad transformer can help refactor event and callback heavy programs into monads via co-routines. The idea is loosely based on Combining Events And Threads For Scalable Network Services, by Peng Li and Steve Zdancewic, in PLDI, 2007. (, but with deterministic and co-operative lightweight threads, also known as co-routines, so that the base monad can be anything ranging from IO to state monads, or your favorite monad transformer stack.
