list, list* | Function |
list &rest objects → list
list* &rest objects+ → result
object — an object.
list — a list.
result — an object.
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.
(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)
(list* x) ≡ x
