vector-append - append vectors
(import (scheme base)) ;R7RS
(vector-append vector ...)
Returns a newly allocated vector whose elements are the concatenation of the
elements of the given vectors.
Returns a single value which is a vector object.
(vector-append #(a b c) #(d e f))
=> #(a b c d e f)
The vector-append in SRFI-43 is identical to the one in R7RS.
[R7RS] It is an error if one of the arguments is not a vector. Implementations
may signal an error, extend the procedure's domain of definition to include
such arguments, or fail catastrophically.
The first RnRS report to carry this procedure is R7RS, which got it from
SRFI-43.
