Yes, that's the weak part of the proposal. I even thought about renaming it to "GROUP BY SOMEHOW" or even "GROUP BY SURPRISE ME". I mean I see some cases when it's useful and much less cases when it's dangerously ambiguous. E.g. grouping by result of a subquery looks way too complex and unpredictable. But with simple Vars... what could go wrong? Best regards, Andrey Borodin.
