I think this is where matrices should act like arrays:
array([[0, 1, 2],
[3, 4, 5],
[6, 7, 8]])
array([1, 4, 7])
in this case, it's not really different types, but totally different
concepts -- indexing with a sequence is different than a scalar, just
like indexing with a slice is different than a scalar.
There are many, many places in python code where we have to make
distinctions between a single object and a sequence of objects that
happens to be of length one.
