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.)
