What does exactly the spec think what an iterable is? As far as I can tell, only `Array.from` and `%TypedArray%.from` test for iterability, and until [bug 2486][] is resolved, it is hard for us to guess, because there are really more than one possible answer, e.g.: `Symbol.iterator in obj` and `typeof obj[Symbol.iterator] === "function"`. Section [The Iterable Interface][1] define something more restrictive than `typeof obj[Symbol.iterator] === "function"` and less testable, given the requirements of the returned value of `obj[Symbol.iterator]()`.
