lisp newbie help

if i set the value of a symbol to a function, how do i call it with that symbol?

(setq a #'append)
(a ... ) <--how do i do this?

thanks

(defun list (list)
 (if (null? list)
   1
   (list (cdr list))))

Who the fuck would do that? That's not a reason for functions and variables to be divided.

Here's how to solve your problem:

[1]> (exit)
Bye.
$ guile
guile> (define a append)
guile> (define x '(1 2 3))
guile> (a x x)
(1 2 3 1 2 3)
