No - no, that's not the point. The assertion it there because pts
shouldn't be out of bounds in the first place; it's a strong indicator
that something's wrong elsewhere. (Not that it seems to break anything
important -- which is why I haven't spent any time on futher digging yet
-- but it's wrong nonetheless.)
After all, that's what assertions are for.
