That works, but I don't think it's satisfactory. first and second
aren't the intended functions to access a map entry's keys and vals—
but most importantly, it's been documented that second is very, very
slow compared to val (http://w01fe.com/blog/2009/01/more-on-clojure-
map-accessor-speeds/).
Just use first and second for both cases.
