Actually, the description for this mailing list says "A list for beginning Perl programmers to ask questions in a *friendly atmosphere*." (emphasis added) I don't see anything about "No schoolwork", or "No puzzles"... And the problem is not simply a puzzle, nor is it homework. If you had read my post more carefully, you would see that I am 1) *teaching* the class, and 2) want to be able to show off one concept (the range operator) before we have talked about another concept (the 'reverse' statement). IM"H"O, if you want to be on a list that is "...for people learning perl who are getting stuck due to pure perl problems..." then start one. I, on the other hand, am staying here.
