Chrome does this for some properties (attributes) but not others
I assume you just meant to do this for attributes? Those are the only
cases in which var would call setters, obviously.
The var shadowing issue is an issue for operations too, of course, but
it sounds like that's being solved on the ES side.
I can live with putting attributes directly on the global. If we ever
add an attribute to EventTarget that will be a little weird because
hooking the getter or setter on EventTarget.prototype will affect all
event targets _except_ the global, but that's life.
