Summary: The idea is to have keys/entries/values/forEach methods on
these two interfaces, so you can do things like:

document.querySelectorAll("whatever").forEach(someFunc)

and

document.body.classList.forEach(someFunc)

Bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1290636

Standard: https://dom.spec.whatwg.org/#interface-nodelist and
https://dom.spec.whatwg.org/#interface-domtokenlist

Platform coverage: all.

Estimated release: Firefox 50.

Devtools bug: none needed.

Other browsers: Chrome is shipping this in stable; no signals from
Safari or Edge.

Noted dev-doc-needed on the bug.

Gentle reminder for everyone to try to remember to put this on any bug
which affects how developers can or should use things. :)

It looks like WebKit landed support recently.

Ah, thanks. I just checked a WebKit nightly, and yes, they support it
in a way compatible with our implementation (unlike Chrome, which is
slightly buggy; see
<https://bugs.chromium.org/p/chromium/issues/detail?id=632935>).
