Hi! I am pleased to announce patterns-0.0.3. On Hackage: http://hackage.haskell.org/package/patterns The Patterns package implements communication patterns that are often used in distributed, message-oriented applications. The package implements a set of basic patterns and a device to connect basic patterns through routers, brokers, load balancers, etc. The package is based on the zeromq library, but abstracts from the notion of sockets, on which zeromq is built.
