The fix proposed in #502 only applies to this specific case. To solve the problem in general, some additional alias logic is required. It's possible to solve a problem by manually giving aliases to the expressions that boil down to the same stripped value, e.g.:

RETURN 1+2, 3+4;           // fails because that's replaced during the query stripping with 0+0, 0+0
RETURN 1+2 AS x, 3+4 AS y; // OK
