  Please listen.  Call _by_ value is different from call _with_ value.  The
  meaning of "value" is irrelevant.  The fact that you cannot access the
  _binding_ of the value is the clue.  In call _by_ reference, you do not
  pass _some_ references to objects, you pass references to _bindings_.
  In a fight against something, the fight has value, victory has none.
  In a fight for something, the fight is a loss, victory merely relief.
