I can see Stefano's point, but there are also advantages in auto-casting a 
1x1 matrix to a scalar. By the way (Stefano, are you there?) if you really 
need to ensure that the result of an operation is a matrix, you can always 
force it via the "matrix" alias, as in

matrix x = foo(z)

So, in my view, there are pros and cons to either choice. I think we ought 
to reach a collective decision here. So my proposal is: everyone 
interested, please have your say now. (Myself, I'd say "auto-cast".) 
Allin, just wait for a few days and then whatever you decide is the law.
