Ouch. Assuming the same path is followed with tuples, I think that this means the following behaviour will continue:

>>> t = (1,2,3) >>> a = array([4,5,6]) >>> t += a >>> t array([5, 7, 9]) That's not particularly desirable.

Why not? It doesn't really differ much from the following example IMO:

x = 3 x += 0.5 x 3.5
