@hackage courier0.1.0.8

Inspired by Erlang's simple message-passing facilities, courier provides roughly similar capabilities. Applications simply create one or more endpoints, bind each to a transport using a given name, then can freely send / receive messages to other endpoints just by referencing the name each endpoint bound to its transport.

Applications may process messages in the order received at an endpoint, or use selective message reception to process the first message arriving at an endpoint that also matches a provided selection function. Through selective message reception, applications may approximate the style of an Erlang application, and enjoy better composability of message reception with multiple independent dispatch routines or message pumps.
