| list?

  Yes.  For two reasons: (1) The values is collects into a list are all fresh
  as far as mapcar is concerned.  (2) Where would it find the old cons cells
  to use?

  It would be really stupid to use `mapcan´ or `mapcon´ with a function that
  returned old cons cells, however.

Act from reason, and failure makes you rethink and study harder.
Act from faith, and failure makes you blame someone and push harder.
