So basically, this is an implementation of GLSL in C++.
You believe the GLSL API should be the standard API for linear algebra. 
But do other people agree? Even in the shading language world, isn't Cg 
more popular?
Aren't those APIs very C-ish? There is no genericity in the types.

You can probably implement a simple DSEL to describe swizzle operators.

Also, I read on your site you require anonymous unions for some things. 
Why is that?
