You can't. nonlocal positional parameters are inacceessable. I'd actually like 
to see a "shiftpop" that returns the value or maybe does an assignment, 
because 99% of the time that's what happens immediately before a shift.

But you were right the first time, there's no reason not to use an array. (well 
i can think of a few corner cases as usual, but... nobody cares)
