[issue9314] inconsistent result when concatenating list with iterators

[Dirkjan Ochtman]

Dirkjan Ochtman <dirkjan at ochtman.nl> added the comment:

Sure, but:

>>> a = ['a', 'b', 'c']
>>> a += 'def'
>>> a
['a', 'b', 'c', 'd', 'e', 'f']

I think either way is fine (I'm probably on the side of refusing to guess), but what I don't understand is why a += b is different from a + b in this respect.
