Hi Konstantin, Thanks for bringing up this discussion. +1 for the idea. We have met this in our company too, and I planned to support it recently in our internal branch.
regarding to your questions, 1) I think it might be more a table/view than function, just like Temporal Table (which is also known as dimension table). Maybe we need a DDL like CREATE VIEW and plus some additional settings. 2) If we design the DDL for it like view, then maybe temporary is ok enough.
