Why don't create a remaining objects array yourself using - containsObject:, -subarrayWithRange:?

Is it possible to get a count of an enumerator without exhausting it? I just want to know how many objects remain in my enumerator, but calling allObjects to get a count exhausts it. I can work around by doing some silly things like creating a new enumerator from the array returned by allObjects after counting it, but it seems like there should be a simpler way. (Plus, I lose functionality from that since -[NSArray objectEnumerator] returns an NSEnumerator and I'm starting with an NSDirectoryEnumerator.

I guess I might just have to file an enhancement request against Foundation to add -[NSEnumerator count], but I'm hoping there's just something I'm missing.
