We did some specs for new main loop.
Hi! I had volunteered to write up the algorithm, and last night I started doing that, but ran into several things we hadn't thought of. I was able to fix most of them, although it made things a bit more complicated, and there's still an issue for the separator.
I've attached my code, which I know sucks, but at least mostly works (it doesn't print the separator when $before == $after == 0).
An actual implementation of this should probably use a circular array (size $before + $after + 1, do all offsets modulo this number). Also, Uri, I must be missing something about references to scalars, because every time I tried to make the last element a pointer, and then deference it, I got an error about strict 'vars', and if I didn't use strict, it didn't work. So I must be confused about something.
