;; Demonstration of JVM dead code elimination in Clojure 1.2 and 1.5
;;
;; This Clojure script demonstrates some of the effects of dead code
;; elimination in the JVM. For unknown reasons, the bytecode produced
;; by Clojure 1.2.1 is more susceptible to elimination than the
;; bytecode produced by Clojure 1.5.1, making it seem like 1.2.1 is
;; faster. But when the code is forced to do real work, the difference
;; disappears.
;;
;; My results with Clojure 1.2.1:

/* Demonstration of dead-code elimination in the JVM.
 * 
 * This class demonstrates some of the difficulties of benchmarking
 * code which may be subject to dead-code elimination by the JVM.
 * There are two loops, both calling the same function. But only the
 * second loop actually uses the result of the function.
 *
 * When I run this code, I get results like this:
