  I see that this simple solution has troubles.
  I think part of the way Mathematica deals with is by doing slick things
with storage, not storing multiple copies of identical objects.  I
understand that .Alias is scary, but would there be any way of using the
same mechanism to keep a buffer/stack/list/whatever of links to previous
answers?
