(1) we aren't going to add the .* notation A1 .* A2 to sage, since there has to be a *very* very strong demand to ever add anything new the preparser. We haven't added anything in as long as I can remember. The last thing I wanted to add (implicit multiplication) even got voted down. (2) I would love to add a fast optimized function that does multiply component wise.
