That fairly trivially resolves the StopIteration behaviour by pushing it out of the ES6 spec.  If there's enough demand for manually creating or 'calling' a generator then we can fix it in ES6.x/7

I was meaning you don't have the ability to directly executing a generator - you can pass it around, hang properties of it, etc but not directly trigger enumeration

so you couldn't go generator.next() or generator() or whatever, but you could go for (... of generator) or [ ... generator], etc
