Dammit. I was thinking about PV for no reason today, and suddenly came up with an idea that would make the parts that always seemed a little awkward to me go away and make the whole thing more seamless (if shorter). Of course it requires substantial rewriting. I said I was done with it! I don't want to do this! I'm going to have to go over it, of course, and I'll probably end up making the changes. Dammit. Why didn't this come up two years ago?
