I meant -- no one is suggesting:
element = M[i][j]
because, of course, M[i,j] is exactly what you should do do get an element.
Which, by the way, brings up another inconsistency in the current behavior:
>>> M
matrix([[1, 2, 3],
[4, 5, 6],
[7, 8, 9]])
>>> M[1,1]
5
>>> M[1,:]
matrix([[4, 5, 6]])
so if you pull out a single element, you get a scalar(0-d), but if you
pull out a row, you get a matrix(2-d). It makes me want vectors more...
