Which is exactly why I offered it as a golfed version only - but I probably should have mentioned that lest someone use the golfed version in production code. Hopefully you've saved someone a world of trouble.

Being an old C programmer, I was taught never to trust the order of evaluation of parameters (right to left, left to right or something in between). But it does seem to work consistently on my version of Perl (5.8.8) - raising the question: does Perl have a defined order of evaluation for parameters or is it like "other languages" and leaves order to the optimizer and compiler implementation? I looked for a citation either way this AM and had no luck.

Best, beth
