Replying to [comment:6 tmonteil]:
> I did it. Does `a**b` not just call `a.__pow__(b)` ? I do not see any
difference with timeit. Note that there are other uses of `__pow__` on the
same file.
As far as I understand: It does. When you do `__pow__` there is an
introspection (= lookup in the dictionary of methods). But for special
methods there are dedicated slots and when you do `**` there is no lookup
since you access directly to this slot.
