In the proposal, the Set constructor takes no arguments.

http://wiki.ecmascript.org/doku.php?id=harmony:simple_maps_and_sets

Could it take a list of initial elements to be included in the set?

var s = new Set('alpha', 'beta');
s.has('alpha'); // true

I think this is a lot better than the verbosity that is

var s = new Set();
s.add('alpha');
s.add('beta');
