Sprry to reply to my own post, but another
small issue is that the generator always
returns nil after it exhausts the collection.

But what if a collection contains nil values?

I think I'd like an 'end?' method or something.
At worst, we could define a meta-nil value, but
I'm betting that's not necessary.
