I was thinking along those lines for some time and I found that with the new standard we could unify matrices and vectors, dynamic and fixed. Here is a working implementation I had started some time ago but as usual don't have the time to complete :) (http://sourceforge.net/p/larray/wiki/Home/) . I also have a local version of linear algebra expressions template library using proto and this generic array but haven't pushed it to source forge yet.
Best,
Nasos

I know we have a fully working Fusion for 0x only. mpl, proto and other strategic infrastructure libraries should benefit from that. Some are a trivial port like Boost.PP and all the TR1 boost library that will just either disappear or forward the C++11 version.
