I don't wan't to to be rude in any way, but i thought Davids reasoning on Array operators: "Using a set probably would have been better, but I didn't know about Ruby sets until after I finished my code. So my solution is a very elegant way of wielding a stone axe." should have found it's way into the summary, especially as all the samples given are wielding the same ancient weapon. or to put it with your own words: "Then you'll want to look at the standard "set" library. That will make your whole weekend." Just a thought of mine, it seemed to be one of the gotchas in this quiz. Keep up the very good work! cheers Simon
