ints are immutable, so they don't implement __iadd__.  lists do:

>>> [].__iadd__
<method-wrapper object at 0x8145f24>

Hmm, I think the issue here is that 

x += y

translates (in the presence of an __iadd__ method) roughly to 

x = x.__iadd__(x, y)

and you can't do that in the form of 

operator.blah(x,y)

.  Or it might just be oversight.

Cheers,
M.
