I've started implementing traits for fixed-length vectors with a few macros:

I don't have Clone yet, but it should be easy to add.
As a side note, looking through your code, this is
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

And an additional question.
3. What is the rationale in having both Copy and Clone? Can one
provide an exhaustive list for where one would want to use Copy
instead of Clone/DeepClone? I tried to use clone everywhere, but I
needed T : Copy + Zero to be able to write, for example,
[Zero::zero(),..
