I think assuming anything about A*B is extremely dangerous.  Just of
the top of my head, Ada and Matlab think it means matrix
multiplication and Fortran and Mathematica think its pointwise
multiplication.

It means basically nothing in C, and in C++ it means whatever the
matrix class implementor wanted it to mean.
