[Numpy-discussion] bug or feature?

[Curzio Basso]

Hi all,

I noticed the following (unexpected for me) behaviour:

>>> a = NA.arange(12)
>>> a.shape = (3,4)
>>> a[[0,2]][:,:2] = a[[0,2]][:,2:]
>>> print a
array([[ 0,  1,  2,  3],
       [ 4,  5,  6,  7],
       [ 8,  9, 10, 11]])

rather than 

array([[ 2,  3,  2,  3],
       [ 4,  5,  6,  7],
       [ 10, 11, 10, 11]])

as I was expecting. This happens only if I try to combine indices
lists with slices.
Is it by design or I ran into a bug?
