But there is not universal agreement that x[0] == x[0,:] is 
desirable.  In contrast, there *is* universal agreement that
x[0][0]==x[0,0] is desirable.  Or so I've understood the 
discussion.

As you know, my view is that nonscalar indexing should
return submatrices, while scalar indexing should return
1d arrays.  Thus I do not see  x[0] != x[0,:] as breakage:
it is desirable.  Indeed, without it, we will have an
untenable situation, under all the different proposals.
So it is a goner one way or another.
