Suppose I have a clojure file called app.clj that contains something
like:
(ns app)
(defn foo [] (println hello))
(defn reader [filename] (load-file filename))
and a file called data that simply contains

What I would like to see, from the REPL, is:
user= (load-file app.clj)
user=

That brings up an important point. The var *ns* may look like a global
variable in C++, but it's really a dynamic variable--something quite
a bit safer and more
