Ah, nice! I now remember briefly thinking that such a thing should be
possible. Interestingly, I just recently wrote a backtracking search,
so I could have used such a thing -- it's a pity that I didn't
remember about send() while I was doing that.
I may have to alter my design to see what happens.
