Syntax:

list &rest objects => list

list* &rest objects+ => result

Arguments and Values:

object---an object.

list---a list.

result---an object.

Description:

list returns a list containing the supplied objects.

list* is like list except that the last argument to list becomes the car of the last cons constructed, while the last argument to list* becomes the cdr of the last cons constructed. Hence, any given call to list* always produces one fewer conses than a call to list with the same number of arguments.

If the last argument to list* is a list, the effect is to construct a new list which is similar, but which has additional elements added to the front corresponding to the preceding arguments of list*.

If list* receives only one object, that object is returned, regardless of whether or not it is a list.

Examples:

 (list 1) =>  (1)
 (list* 1) =>  1
 (setq a 1) =>  1
 (list a 2) =>  (1 2)
 '(a 2) =>  (A 2)
 (list 'a 2) =>  (A 2)
 (list* a 2) =>  (1 . 2)
 (list) =>  NIL ;i.e.,  ()
 (setq a '(1 2)) =>  (1 2)
 (eq a (list* a)) =>  true
 (list 3 4 'a (car '(b . c)) (+ 6 -2)) =>  (3 4 A B 4)
 (list* 'a 'b 'c 'd) ==  (cons 'a (cons 'b (cons 'c 'd))) =>  (A B C . D)
 (list* 'a 'b 'c '(d e f)) =>  (A B C D E F)
