you can have both of them:

        union
        {
                struct { Type x,y,z; };
                Type v[3];
         };

that's what I used for my small vector3d (and vector2d, quaternion, matrix3) library.

btw, I really would like to see boost with some kind of small vector
library, that most importantly allows multiplacation of vector3d by
quaterion to acheive rotation in 3d space. Conversion from quaterion to
axis-angle, to euler-angle, to rotation matrix representation of
rotation, etc...

Currently I'm dragging everywhere my library, and I use it in a lot of
different projects. Anyway if you are interesed in that 3d stuff let me
know, and I'll start a code cleanup to eventually submit it to boost :)

And if someone already works on that I really would like to know about
that (so I can help)!
