For even more fun, checkout hy (https://github.com/hylang/hy). It's completely compatible with standard python both ways (ie you can import python from hy and import hy from python), so you can import python-sh and do awesome stuff like:

  (import [sh [cat grep wc]])
  (->
   (cat "/usr/share/dict/words")
   (grep "-E" "^hy")
   (wc "-l"))

It isn't clojure compatible, it is like clojure.
