This ([1]) is just so cool - it even got me to read it properly. Which did get me pondering on why people might feel the need to re-write Universal/Empty to Top/Bottom, making people have to just remember the terms, since hopefully many users will have no idea why. But it is really good, and even seduces me into thinking I might understand it.
