Haha, I am now. I haven't followed the entire discussion because beyond a
certain point it was hurting my head to think about it.

I do like the idea of knowing which is the "first" and "last" index without
manually using a flag or something. For those who may be interested, I once
wrote a little piece of code illustrating my idea of a "super-iterator."
This idea had its problems, and it was never fleshed out. But I still like
many of the motivations behind it.
