BLADE 0.2Alpha: Vector operations with mixins, expression templates, and asm

[Mikola Lysenko]

Excellent work!  I have to say that I've had my misgivings about mixin 
statements, but I'm glad to see that BLADE and Don's hard work have 
proven me wrong.  Compile time vector expressions are desperately 
needed, and this library goes a long way to sorting things out.  As far 
as meta-type tricks go, this is by far the coolest I've ever seen in any 
  programming language.

One very interesting application I would like to see with this technique 
would be a compile time geometric algebra library.  If no one writes one 
by this summer, I will probably do it myself.  (Actually, when I heard 
the name BLADE, my heart skipped a beat thinking it was a GA library, 
but alas it is not...)  Maybe it is my unrestrained exuberance, I would 
guess that a strong D implementation should easily crush the leading C++ 
GA lib, GAIGEN in both performance and ease of use.
