associative list won't append variable contents

[Dr. Shred]

Hi,

(setq car-0 foo-0)
(setq cdr-0 foo-1)
(setq file-list (append '((car-0 . cdr-0)) file-list))

I want the contents of car-0 and cdr-0 to be the actual
car and cdr.

Lisp creates

((car-0 . cdr-0))

not

((foo-0 . foo-1))

Shouldn't this work?
