Clojure example of lightweight data modelling

clojure_maps_and_lists.clj

(ns cljtests.data)

(defn main []
  (let [some-items [1 2 3 4]
        some-mapping {:ST "started", :IP "in progress", :DN "done"}]
      (doseq [item some-items]
        (println item))
      (doseq [[key val] some-mapping]
        (println (str key " => " val)))))

(defn -main
  [& args]
  (main))

The starting point for this discussion was:

https://gist.github.com/amontalenti/8114359

Then, @jpfuentes2 shared this example, which is similar but doesn't quite capture the same thing as the Java & Python examples, IMO:

https://gist.github.com/jpfuentes2/8117271

This is a rewrite of that example to be closer.

Here's the full set:

Python: https://gist.github.com/amontalenti/8114383
Java: https://gist.github.com/amontalenti/8114359
Clojure: https://gist.github.com/amontalenti/8117294
Scala: https://gist.github.com/csoma/8115672
C++11: https://gist.github.com/csoma/8115693

Nice, that example is certainly more symmetrical. Minor suggestion:

Place all trailing parentheses on a single line instead of distinct lines.

Thanks! Updated to reflect that style consistency.
