ANSI Common Lisp  14 Conses 14.2 Dictionary of Conses
- Syntax:
-
rest
list
 tail
(setf
(rest list) new-tail)
- Arguments and Values:
-
list - a list,
which might be a dotted list or a circular list.
tail - an object.
- Description:
-
rest performs the same operation as cdr,
but mnemonically complements first.
Specifically,
(rest list) ==(cdr list)
(setf (rest list) new-tail) ==(setf (cdr list) new-tail)
- Examples:
-
(rest '(1 2)) (2)
(rest '(1 . 2)) 2
(rest '(1)) NIL
(setq *cons* '(1 . 2)) (1 . 2)
(setf (rest *cons*) "two") "two"
*cons* (1 . "two")
- See Also:
-
cdr,
nthcdr
- Notes:
-
rest is often preferred stylistically over cdr
when the argument is to being subjectively viewed as a list
rather than as a cons.
- Allegro CL Implementation Details:
-
None.
