There's one more, even more obvious (IMO) option for an empty set literal: U+2205, EMPTY SET. But that opens a whole other can of worms, namely expanding the grammar to allow Unicode characters outside of identifiers.

At least the concept of "empty set literal" has more merit than "save a few keystrokes on the word 'lambda'". Even if it isn't something easily typed, it would have value over the current spelling of "set()", which isn't a literal. (Whether it has *enough* value over set() to be worth doing is still in question, but it's not like lambda vs λ.)
