> It seemed necessary to implement a proper `__eq__`, i.e. not to have
equality by id, since we cannot afford equality by id when relaxing the
unique representation, otherwise the pickling test `loads(dumps(M)) == M`
would failed, since obviously `id(loads(dumps(M))` differs from `id(M)`.
Can't you just drop that test? I don't think it's something that has to be
true:
{{{
sage: A=object()
sage: loads(dumps(A)) == A
False
}}}
