For the purpose of giving the most reasonable answer to the `if (OBJ is Iterable)` test that Caitlin Potter was asking for earlier in this thread.
For me, the answer should be the same as what makes `Array.from` choose between the branch "iterable" and the branch "array-like". Which, as I have said, I cannot guess until bug 2486 is resolved. Deeper philosophical thoughts over what an iterable *really* is don't matter.
