object—an object.
generalized-boolean—a generalized boolean.
Returns true if object is of type vector
;
otherwise, returns false.
(vectorp "aaaaaa") → true (vectorp (make-array 6 :fill-pointer t)) → true (vectorp (make-array '(2 3 4))) → false (vectorp #*11) → true (vectorp #b11) → false
(vectorp object) ≡ (typep object 'vector)
