USING might be just as content-free as WITH, but USING OPERATOR seems clearly better, at least IMO. Also, this patch has not been updated in a week, and the clock is ticking: if we don't have an updated version RSN, we need to move this to Returned with Feedback and wait until next CommitFest. That would be too bad; this is an awesome feature.
