For each Ruby module/class, we have Ruby methods on the left and the equivalent
Clojure functions and/or relevant notes are on the right.

For clojure functions, symbols indicate existing method definitions, in the 
clojure namespace if none is explicitly given.  clojure.contrib.*/* functions can
be obtained from http://github.com/kevinoneill/clojure-contrib/tree/master,
ruby-to-clojure.*/* functions can be obtained from the source files in this
gist.

If no method symbol is given, we use the following notation:

(require 'clojure.test)

  [name-string & body]
  (let [name-symbol
        (-> name-string

          (clojure.string/replace #"\W" "-")
          (clojure.string/replace #"-+" "-")
