I can see why you might want it, and at the moment I can't remember
why it's not there. Perhaps something to do with the problem of
creating the access value? (it would force the item in the Container
to be aliased, thus constraining it .. I know this actually happens in
the BCs but I was very unhappy with the necessary kluge).
