Yes, I am very sorry.

Raises a warning instead of error. Would need to check Sybase and DB2, but ...

Yes, good. Do we want this in 7.1.0 ? Seems, yes :-(

No, pretty sure this will not fly for the 7.1.x cycle, no matter what we
end up deciding is the best approach (with SQL9x getting more votes than
most other proposals, but The Right Thing having the most votes of all
;)

We are at the tail end of the beta cycle, and a change in behavior which
is this fundamental needs more time and discussion. All imho of
course...

No way.  I'm just giving some food for thought while development is slow.

In any case there seems to be support for the proposed feature.  I'm just
waiting for someone to complain that he relies on the existing behaviour,
but I doubt that.

I agree this change is very good idea, but 7.2 is probably a better target.
