The __bases__ property is defined by the metaclass, "type". dir() of a
class doesn't show attributes from the metaclass [1].
Because dir() is supplied primarily as a convenience for use at an
interactive prompt, it tries to supply an interesting set of names
more than it tries to supply a rigorously or consistently defined set
of names, and its detailed behavior may change across releases.
For example, metaclass attributes are not in the result list when
the argument is a class.
To see the metaclass attributes use dir(type(Carre)).
