Is whitespace between q and the delimiters still valid? Would it be after <<? Would that mean using q as the first element in a qw-list will hurt? I hope the first answer is 'no' and all other questions are thus rendered irrelevant. Not that I think getting rid of alphanumeric delimiters is a good idea, though. I just fear complex parsing and seemingly random syntax errors. Juerd
