Yes, must be removed.
Or I must test `self.exp.is_complex` instead of `self.base.is_complex`.

Well, I have to consider the logic of Pow._is_irrational more precisely.
By the way, for Add class I did not found out the `is_complex` method, so e.g. `(S(1) + I).is_complex` gives None, instead of True.
