Rule 1 stoped being a useful rule when we lost rule 2.

I do think it's possible to make this change. I very much think the
behavior that is being proposed is more intuitive (and tellingly I
haven't seen anyone argue otherwise). IMO there are three questions
that are relevant for deciding whether we should do this.

* What will break?
* What does it cost us in complexity?
* What does it cost us in performance?

None of those questions (or their answers) involve invoking Larry.
