Yeah, that is a cool feature. They're called newtype structs, after
newtypes in Haskell, discussed in the tutorial at
http://static.rust-lang.org/doc/tutorial.html#tuple-structs
btw, updated that gist w/ a hacky impl of Clone that uses copy, which I
think I've heard is going away in the near futu

As a side note, looking through your code, this is cool:
