Especially given this:

(ns dda.main
  (:gen-class))

(def should-exist "Do I exist?")

(defn -main [] (prn (str should-exist \space (ns-name *ns*))))



The (def) is evaluated, since should-exist is found when -main is called 
from the generated class, but why isn't (ns) evaluated? Which should have 
changed *ns* to "dda.main".
