Not to sound too dense, but doesn't Perl always use "pass by reference," in that changing anything in the $@ array will change its values in the calling routine?

Of course, the language I grew up using always passes by reference, so it usually takes a mental effort to assume any changes in a sub to passed variables don't propagate upstream.
