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. -- Erik Naggum, Oslo, Norway Act from reason, and failure makes you rethink and study harder.
