just trying to get a gut-grip on these four array processes, and I'm
pushing and popping and shifting and unshifting left and right (and back

does anyone think this is a naming convention that could benefit with
some change, or am I just being strange?
<http://en.wikipedia.org/wiki/Stack_%28data_structure%29#Operations>
The way I think of a stack is as, literally, a stack of plates. A
cafeteria with a stack of plates where the stack is placed on a spring so
that when one plate is picked up (popped), the one below pops up and can
be accessed. The other plates aren't accessible because they're in the,
err, cabinet. When a plate is put on the stack, of course, it pushes
down the other plates.
