c++ (read object oriented) handling of entities like

    C = a*A*B + b*C

in contrast to uBLAS:

    C = a*prod(A, B) + b*C //citation from uBLAS docs

don't get what you mean by that
they are already splitted

actually it's rather trivial
specialize a template for concrete expression to your taste and you are done

that is the hardest part i suppose
but i'm sure it is achievable
