Is this just an issue with XrayWrapper?
(In reply to Boris Zbarsky (:bz) from comment #1) > Is this just an issue with XrayWrapper? That would match what I'm seeing.
[x for (x of top.opener.content.document.body.wrappedJSObject.childNodes)] works as expected.
Triage question: Dão, how high priority is 737792 for you?
Bug 737792 isn't a priority. I nominated this because I wasn't sure if this could affect web content. If it can't, it probably doesn't need to be fixed immediately, although it would be nice for chrome JS (Firefox, add-ons, etc.).

It's not a standard yet, and it shouldn't affect web content, so I won't bother release drivers with it. I think it's still a relatively high priority for us (unless Jason has a different opinion), because we do want for-of to work correctly and developers to experiment with it.
