  Yes.  Passing pointers is not the same as pass-by-reference.  "Pass by
  reference" means that a reference to the storage of the value is passed,
  but the value in Common Lisp is a pointer or a number/character.  Common
  Lisp does _not_ pass a pointer to the pointer-or-number/character.
  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.
