You left off Tuple, perhaps because it also broke the simple pattern:
Tuple 1, 2 (1,) ()
Still I see no reason to repeat the confusion to save one pair of
braces (square or parenthetical). Starting the language over I could
see making {:} and {} the empty dict and set respectively, but not
with the history Python has.
If people are dead set on a set literal, why not look further, to
atrocities like <1,2>, <1>, <>; @{1,2}, @{1}, @{}; {{1,2}}, {{1}},
{{}}; etc.? I know there has been resistance to grouped <> before (not
for sets), but I can't remember why.
