What are transducers? A live(ly) explanation: http://cloxp.lively-web.org/clojure-doc/transducers.html
@robertkrahn: I love transducers and am trying to make good use of them when I can. I've been working on some L-System code which ought to lend itself to transducers, but I've been struggling to figure out the best way to do that. If you have any suggestions the code is here: https://github.com/decomplect/ion/blob/master/src/ion/ergo/l_system.cljc
