He's apparently talking about Clojure's thread macro specifically. If you're not familiar it can be a way to organize code in a straightforward, human-readable, easily debuggable syntax. Ex: (~> (sha1 in) (bytes->hex-string) (bytes-append #".") (displayln)) In pseudo-Python this would be: displayln(bytes-append(bytes->hex-string(sha1(in)), #".")) http://www.greghendershott.com/2013/05/the-threading-macro.html http://www.greghendershott.com/2013/05/the-threading-macro.h...
