What is the argument that this occurs often enough to be worth expending extra cycles and code space on?
If we do do something like this, I'd be inclined to make it handle any-number-of-consecutive-NOTs, and maybe remove NOT NOT over an ANY, not just EXISTS. But I don't honestly think that it's worth troubling over. Do even the dumbest ORMs generate such code?
