Bump. I'd still like to hear about this. The docs have a *huge* box saying that iOS NSPointerArray is not doing __weak references, but it sure looks to me like it is. But I don't know how to test. Thanks for any help. m.

So are the docs just lying (in a big bold box right at the top), or is this some other kind of weak reference (i.e. somehow weak, but not ARC-__weak)?
