numpy.repeat(2, 3) returns np.array([2, 2, 2]) but 2to3 confuses it with the old operator.repeat.  It may be impossible to resolve in general which function the author wanted to call but perhaps the warning should only be raised if the operator module is imported at some point?  (or clarify the error message)
