No way.
So *if* ``x[0]`` is going to be 1d to fix the many anomalies that have surfaced, then you would still want ``x[0]==x[0,:]``, but to have those be 1d and have ``x[i, :]*A*x[:, i]`` work would require (oriented) "vector" objects, so you would want those. Is that a fair summary of your view? Cheers, Alan Isaac
