Hmm - I think I am hitting a related bug/feature/surprising change in
behavior, which is showing up rather obscurely in a failure of the
scipy.io matlab loading tests:

http://projects.scipy.org/scipy/scipy/ticket/258

Here's the change I wasn't expecting, present with current SVN:

a = arange(2)
b = arange(1)
c = array([a, b], dtype=object)
c
->
array([[0, 1],
       [0, 0]], dtype=object)

On a previous version of numpy (1.02b.dev2975) I get the answer I was expecting:

array([[0], [0 1]], dtype=object)

Best,

Matthew
