The ellipsis is alredy valid python syntax elsewhere:

In [7]: a=arange(3**3)

In [8]: a.shape=(3,3,3)

In [9]: a[:,...,:]
Out[9]:
array([[[ 0,  1,  2],
        [ 3,  4,  5],
        [ 6,  7,  8]],
       [[ 9, 10, 11],
        [12, 13, 14],
        [15, 16, 17]],
       [[18, 19, 20],
        [21, 22, 23],
        [24, 25, 26]]])

I don't think it would be a good idea to make it do this kind of double-duty.
