Actually, it looks like 4. would have prevented 5. and 6. from ever being executed. Perhaps it would work if I just changed that to "If you can, move left and goto 1".
In any case, I've come up w/a real class. This one just presumes that your set will be composed of integers from 0 to n - 1. I'll work on a template later that can work w/sets of any type. What do you think? I've also made what I think is a portable test suite for it.
