have the sum function call first_object._sum(list of things to sum) if it
exists, and make a _sum method that does a Graphics3dGroup(sum_list)
behind the scenes? This would also help with a recent ticket that ncohen
opened about sum being really slow for linear programming stuff.

Actually, I just checked, and something like it is already being done. If
you do sum(something,...), then if something has a sum method, it is
called: something.sum(...). Of course, this won't work with lists or
generators.
Anyways, feel free to review this ticket!
