It seems far too late to be considering any major rewrite for v12;
even assuming that there was consensus on the rewrite being an
improvement, which I bet there won't be.
"Two or three weeks from now" we'll be thinking about pushing 12.0
out the door. We can't be accepting major definitional changes
at that point.
If a solid case can be made that ECPG's DECLARE STATEMENT was done
wrong, we'd be better off to just revert the feature out of v12
and try again, under less time pressure, for v13.
