A generator function is still a function, and |this| binding is orthogonal to
yield making the surrounding function a generator:
js> function gen() { yield [this, 1]; yield [this, 2]; yield [this, 3]; }
js> var obj = {foo: gen, toString: function(){return "[obj]"}}
js> var a = []
js> for (v in obj.foo()) a.push(v)
3
js> a[0][0] === obj
true
js> a[0][0] === obj
true
js> a[1][0] === obj
true
js> a[2][0] === obj
true
js> a.toString()
"[obj],1,[obj],2,[obj],3"
We'll clarify this in the strawman.
