For what it's worth, I'd love to see TC39 take on Promises. If they
are called "Future" or not matters less. I pushed for DOMEvents to be
dropped from Futures with one of the goals being to make them less DOM
dependent and more possible to spec in TC39 (I had other more
important goals too, I'm not particularly a fan of DOM Events).

In particular, I'd love to get TC39 to look over the "is-a-future"
issue. I'm pretty worried about the current solution which makes
"then" a magic property name. It's less bad than "__proto__" is, but
not by a lot.

However I also think it's critical that we get promises/Futures soon.
We've been writing specs for a long time which suffers from the lack
of them. We're probably permanently adding APIs to the web platform on
a monthly basis which would be significantly improved if we used
promises. Waiting until ES7 is simply not an option.

I don't have any solutions to propose. But I'd be happy to see Futures
removed from the DOM spec once there is a TC39 draft that we can point
to and start implementing.
