I don't know what is a determinist way for enumeration and who is right
(I would be more enclined to keep the chronological order of property
settings but if the strawman says the contrary there must be a good
reason), but not knowing about #164, I wrote one day :
https://code.google.com/p/v8/issues/detail?id=2353
This was closed about 2s after I wrote it, but here what is not
determinist at all is that the enumeration order can change depending on
what you are doing.

Hi,
I've seen a bug report on Firefox [1] and was wondering whether
deterministic property enumeration [2] was still on the table for ES6.
My comment from that bug:

Ignoring the SpiderMonkey threshold, we do have
http://wiki.ecmascript.org/doku.php?id=strawman:enumeration. It was
not promoted to harmony:proposals status for ES6. It's a bit late to
jam in, but implementations along with that strawman should try to
converge. I doubt the threshold will find consensus.
There's a long V8 issue on enumeration not using insertion order:
http://code.google.com/p/v8/issues/detail?id=164 I believe. Closed:
WorkingAsIntended, still drawing fire from developers.

Thanks,
