  How could it be _unknown_?  That would mean delete would have to do
  some weird shit to the list structure while returning the well-
  defined result.

  What are you really getting at?  This subthread got derailed because
  you made a claim that is just plain wrong.  Please ignore it, don't
  try to defend it, and get back to your real issue.

  If this is not what you expected, please alter your expectations.
