;; Channels-driven concurrency with Clojure
;; Clojure variant for code examples from this gist:
;; https://gist.github.com/3124594
;; Primarily taken from Rob Pike's talk on Google I/O 2012:
;; http://www.youtube.com/watch?v=f6kdp27TYZs&feature=youtu.be
;;
;; Concurrency is the key to designing high performance network services. 
;; Clojure provides several concurrency primitives, like futures/promises, atom, agent etc.
;; There is no implementation for "Go channels" in core, but we can use
;; 3rd-party library Lamina to do the same things.
