How to end / Force a close to a program (in Clojure)

Question

Given that part of the attractiveness of Clojure is that you can use Java class libraries, why not just do:

(System/exit 0)

For a more complete reference, you call any Java classes static methods by specifying

(my.package.class/staticMethodName arg1 arg2 etc)

java.lang.* is loaded automagically for you already though if it where not you could call it with

(java.lang.System/exit 0)
