Now, David, you can take a few minutes to tell us *why* it works.
Peeler and I have already squared off over that and returned to our cor-
ners. I just figured, what kind of score would reach an extreme for
matching once, outside the range of results for zero or two ore more?
It had to involve a convergent series. If the goal were to match on 0
or 1 but not on 2 or more, this would do the job:
* 1.1^0
* -1^.5 regexp
but so would
* 2^0
* -1^1 regexp
When there's a concern about finding dozens of matches and wanting to
abort on the second instead of continuing to look when it no longer
matters, your infinity shuffle handles that:
* 2^0
* -2147483647^0
* -1^1 regexp
* 9876543210^0
