FWIW, I think the easiest and most readable syntax is:

    mySet = set(1, 2, 3, 4)

BTW, this is a bit reminiscent of the discussion about a syntax
for entering fixed decimals.  After much discussion, someone
realized the obvious and noted that real programs mostly
take in their fixed point data from external sources and would
rarely appear as a constant in a program; hence, there was no
need for a special syntax -- just Decimal(data) would do the
trick.  (Think about a program like Quicken for checkbook
accounting -- none of the check/deposit amounts are known
in advance so the program is unlikely to contain any fixed
decimal constants except zero and $0.01).
