Returns a newly allocated vector whose elements contain the given arguments.
Some implementations allocate a new object every time this procedure returns an
empty vector. One such implementation is Chicken 5.2.0. Other implementations,
like Chez Scheme 9.5, return the same empty vector object every time.
Returns a newly allocated vector.
If this procedure is called without arguments it returns the empty
vector, which may or may not be newly allocated.
(vector 'a 'b 'c) => #(a b c)
; Newly allocated vectors are mutable:
(define x (vector 'a 'b 'c))
(vector-set! x 0 'A)
x => #(A b c)
; Vector literals are immutable (but implementations may or
; may not catch this error):
(define x '#(a b c))
(vector-set! x 0 'A) => error
; Implementations are free to choose if they use one or
; multiple objects to represent the empty vector.
(eq? (vector) (vector)) => #t or #f
Applications should avoid calling this procedure with an unknown number of
arguments. The arguments are passed on the stack, which may not be able to
handle a very large number of arguments. A better way to convert a list to a
vector is with the list->vector(3scm) procedure.
The vector procedure enjoys wide support across Lisp dialects.
This procedure does not raise exceptions, but it may cause an out-of-memory
condition which generally cannot be handled.
