Concurrent Channels
With core.async Clojure includes the notion of channels. This line of thought began life with Sir C. A. R. Hoare in Communicating Sequential Processes [Hoa78],[83] but the theory was expanded into a much more complete form in 1984.[84]
Channels add to Clojure’s concurrency support by providing thread-independent activity queues through which processes can communicate. It cleanly solves the information-exchange problems that have spawned mechanisms like callbacks and observers.
