I believe that this is exactly the sort of language-specific behavior that PMCs were designed to solve.
Yup. But in this case the bounds checking is needed if you care, since:
$bar = pop @foo;
should return undef if @foo is empty. Call it a thousand times and you should cheerfully get a thousand undefs. If code wants to see if there's actually anything in @foo, then it has to check. (In the perl 5 case, of course)
That should happen regardless of the language popping an element off of @foo.
