Is array() really the best way to copy an array? I would have thought m_i = m_o.copy() would be better - requiring less of array's clever guessing, and preserving subtypes. On the downside it doesn't work if you're given a list, but perhaps np.copy() would be better (though it loses subtype information)? Certainly it's clearer.
