Pipes: Compositional and Effectful Stream Programmming

David McHealy will present the pipes library. Pipes decouple stream processing stages from each other so that you can mix and match diverse stages to produce useful streaming programs. If you are a library writer, pipes let you package up streaming components into a reusable interface. If you are an application writer, pipes let you connect pre-made streaming components with minimal effort to produce a highly-efficient program that streams data in constant memory.
