I'm curious why you guys think you *need* an empty set literal.
The current spelling using set() and frozenset() is unambiguous.
So what's the point of trying to shoehorn-in a new literal?

AFAICT, this discussion has been solely motivated by
a shallow itch, "dicts have one, so sets have to have one too".

If there were a clean, beautiful, obvious correct answer,
it would have already been done.   Since there isn't,
we have to ask, who cares?
