pylint #9334 C0103 false positive on __class__ [rejected]

When run on this code:

class Clazz(object):

    def changeType(self, newClass):
        self.__class__ = newClass

pylint issues this message:

C0103:  4:Clazz.changeType: Invalid name "__class__" (should match _?_?[a-z][a-zA-Z0-9]{1,30}$)

It is true that the name "__class__" does not match the configured naming convention. However, since it is a builtin Python name, changing the name is not possible.
