You not only have to fix the descent in dimensions, you will have to fix PyArray_From DescAndData (or whatever it is). I vote for simply noting that x = array([a, a]) won't work, and keep it around as a reminder of what a horrible mistake the current Matrix implementation is. The code is difficult as it is, and if we keep this up it will start looking like windows with 15 years of compatibility crud. Chuck
