THAT is what I believe is needed in a "basic" matrix and vector
library, plus operations on those types.

Emil, can you include a collection of such types with the library?

The scenario I'm thinking of is this:

New employee: Phil, how do we do matrices for affine transforms?

Me: Just #include this and use types called floatvec2 and floatmat2x2
and + and * just work.

New employee: Wow, that's almost as easy as Java!

Versus:

New employee: Phil, how do we do matrices for affine transforms?

Me: First, define your own structs.  Then define partial specialisations
of these two type traits templates.  Now #include this, and + and * will
just work.

New employee: Poo, you lost me at "partial specialisation".  I think
it's quicker just to write my own matrix multiplication function.

Cheers,  Phil.
