Calls procedure with the elements of the following list as arguments:
(cons* object object …)
The initial objects may be any objects, but the last object (there must be at least one object) must be a list.
(apply + (list 3 4 5 6)) ⇒ 18
(apply + 3 4 '(5 6)) ⇒ 18
(define compose
(lambda (f g)
(lambda args
(f (apply g args)))))
((compose sqrt *) 12 75) ⇒ 30
Returns #t if object is a procedure; otherwise returns
#f. If #t is returned, exactly one of the following
predicates is satisfied by object: compiled-procedure?,
compound-procedure?, or primitive-procedure?.
Returns #t if object is a compiled procedure; otherwise
returns #f.
Returns #t if object is a compound (i.e. interpreted)
procedure; otherwise returns #f.
Returns #t if object is a primitive procedure; otherwise
returns #f.
Returns the closing environment of procedure. Signals an error if procedure is a primitive procedure, or if procedure is a compiled procedure for which the debugging information is unavailable.
