Nah, `__prepare__` very much predates stable dicts and that problem was solved differently. On Mon, Nov 28, 2022 at 4:46 PM Greg Ewing <gcewing@snap.net.nz> wrote:

"Sets weren't meant to be deterministic" sounds like a remnant of the old philosophy, where we said the same about dicts -- until they became deterministic without slowing down, and then everybody loved it.
I got the impression that there were some internal language reasons to want stable dicts, e.g. so that the class dict passed to __prepare__ preserves the order in which names are assigned in the class body. Are there any such use cases for stable sets?
