I don't know that I have anything to add to the arguments already made
in this thread -- and I consider those arguments sufficient.
As to the above argument against, I don't understand it. In the
absence of proxies and with a non-deterministic update order, any
outcome by the new proposed ES6 rule is an allowed outcome by the ES5
rule. In this sense, it is not even a breaking change. The only
remaining objection above I see is "is a waste". I don't care about a
bit of extra runtime overhead in the thrown-error case.
