interesting idea. Given the fact that in 2-d euclidean metric, the Einstein summation conventions are only a way to write out conventional matrix multiplications, do you consider at some point to include a non-euclidean metric in this thing? (As you have in special relativity, for example)
In my experience, Einstein summation conventions are quite incomprehensible for people who haven't studies relativity (they aren't used much outside some narrow fields of physics). If you start adding metrics, you'll make it even harder for people to follow.
My 2 cents,

Just to dispel the notion that Einstein notation is only used in the study of relativity, I can personally attest that Einstein notation is used in the field of fluid dynamics and some aspects of meteorology. This is really a neat idea and I support the idea of packaging it as a separate module. Ben Root
