I might agree with this, but would not recommend special syntax for it. In

Without a lot of hackery or post-parse validation (e.g. at byte-compile
time), the above syntax is not possible.
I think the follow is just as readable, if not more so:
>>> s = set(1, 5, 7)
Where set() is a new builtin, taking an arbitrary number of arguments and
returning a new Set type.
The rest can easily follow once you have a Set object in hand.
