I agree.

And maybe it's not surprising that these attempts failed. It's not that easy
to get the generalization exactly right. In a production environment it
makes sense to just write some ad-hoc types rather than spend months on the
perfect matrix class; but I do expect this sort of care in a Boost library.
Anyway I personally could care less about computer graphics, fixed-size
matrices are also useful in computer vision, robotics, and no doubt other

Kornel's application looks quite good to me; it would be terrific to see
some real review-ready code come out of this.
