2) Remove it from both the default constraint set and -Wall.
Doesn't that mean that 8.2 will be in ''precisely'' the same situation as 8.0, and we'll just have the identical conversation then? What is `-Wlint`? Is it the same as `-Weverything`? What does it mean? Perhaps this: * Default warnings are what you get by default. Is there a flag `-Wdefault`? * `-Wall` means a larger set. * `-Weverything` means the entire set. Plus there is some protocol that a new warning always starts in `-Weverything`; may move in the next release to `-Wall`; and may move in the release after that to the default set. Both moves are a judgement call. Maybe I have this wrong. It would be super-helpful if someone could lay our the entire proposal. It doesn't look hard to implement in 8.0 if I have it roughly right, and someone is willing to step up to do it.
