unique representation, otherwise the pickling test `loads(dumps(M)) == M`
would failed, since obviously `id(loads(dumps(M))` differs from `id(M)`.

be true:
Well actually this is part of the `_test_pickling` method, as defined in
`sage/structure/sage_object.pyx`. So shall we run the test suite as
`TestSuite(M).run(skip='_test_pickling')` or shall we redefine
`_test_pickling`?
