Why not modify Boost.uBlas so that it uses vectorization, then use
Boost.uBlas as a basis to write other vectorization-aware libraries?

Introducing a new library that does it then rewriting Boost.uBlas in
terms of that library seems to be more work; especially since both
libraries would have a very similar interface.

I have used the GCC vector intrinsics, yes.
I didn't find it that hard. At least much easier than writing inline

Reading that sentence, however, I'm not too sure we're talking about the
same thing.
Are you saying those intrinsics aren't enough to generate optimal code?
