What about objects with anomalous interfaces? E.g.,::

    >>> import numpy as np
    >>> x = np.mat('1 2;3 4')
    >>> x[0][0]
    matrix([[1, 2]])
    >>>

Fixing this has been under discussion for the 1.1 release 
for some time now.  To my recollection, no users of matrices 
objected, and the abstract objections from non-users 
subsided.  It would be very disappointing for the 
possibility of fixing this to go away.  The fix appears to 
be a very small change in __getitem__:
