Consistency. a op=b is almost the same as a = a op b except 1) 'a' is computed only once and 2) if a is mutable, type(a) may choose to do op in place via the call to __iop__ instead of __op__. But in any case, the assigment is made and 'a', if a name, is bound to the result. Anyway, this will not change for 2.x and further discussion is really c.l.p. material.
