There are practical problems: Timers on computers are ofen not accurate, especially if any pther processes are running, when it can be difficult to distinguish your CPU time from theirs. Times on some computers have even been found to run backward occasionally. And there's garbage-collection time, which happens now and then. The amound of garbage collection effort your code causes shouls also be measured, even tuough it might happen after your code is finished. -- hendrik _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/users
