That, and to make it MUCH easier to create adapted iterators, and to
make it possible to add arbitrary constructors to iterators, and to
clean up the whole "extra state goes in the policies" fiasco, and...

Basically, as good and useful as the original iterator adaptors design
was, we eventually realized we could do WAY better.

That's not hugely in flux anymore. It should be fairly safe to work
with, having confidence that you won't have to completely throw out
