What do you mean? I can think of two solutions: 1) Track the duplicate references at the parser level and then embed "hidden variables" similarly to how it was done for COALESCE. 2) Create artificial context/stream for the every RSE and store expression results from the select list there. The former one looks "bulky" to me, the latter one will degrade the raw performance due to the extra memory copying. Am I missing anything?
