Is for..of on live DOM nodelists supposed to correctly iterate even when

I believe the current behavior is identical to what would happen with an
array here. Consider http://jsfiddle.net/hpmHg/3/
The core issue here is that for..of iteration does NOT snapshot anything
(unlike for..in iteration).
We could change the iterator to somehow adjust its position internally
on DOM mutations, but defining exactly how that should work is not quite
trivial.
Is there a simple way to do this correctly?
for (var x of Array.from(list))
to explicitly snapshot? Cross-browser compat might not be great so far,
but it's not for for..of either.
