But that last sentence means that the user cannot trust that the list
returned by the accessor will remain intact; a safely-conscious user
would have to copy it before saving it away (or engaging in any computation
that might end up sharing with that list); your average user will think
that they can get away without copying it, and a small number of them will
be saldy mistaken on that account and will end up saddled with a subtle bug.
OK, I give in on this point. I agree with you that it isn't in the
spirit of the MOP to give users this value which can change at any
time. Unless anyone objects, I will go back and change all of these
in the way you mention.
