A few comments:

That assign from @_ idiom may still be relatively common, but it's not recommended these days. While Conway does use the @_ assign throughout his "Object Oriented Perl", now his "Perl Best Practices" recommends using shift to access @_.

And myself, I'm having trouble reproducing this problem at present. I just made a quick try at comparing assigning an array vs shifting off of an array, and I find that they've both gotten slightly faster under perl 5.9.5 vs perl 5.8.8 on my AMD64 based laptop, running kubuntu (linux kernel: 2.6.22-14-generic).

And incidentally, I see that the "shift" method is around 30% faster than assign from array.

(Benchmark code available upon request. At present I'm just skipping it because it's fairly dull.)
