The external representation of instances of the datatype XXXvector is #XXX( ...elements... ).

For example,

#u8(0 #e1e2 #xff)}}  ; a {{u8vector}} of length 3 containing 0, 100, 255
#f64(-1.5)           ; a {{f64vector}} of length 1 containing -1.5.

This external representation is also available in program source code. For example,

(set! x '#u8(1 2 3))

will set x to the object #u8(1 2 3). Since CHICKEN 4.9.0, literal homogeneous vectors do not have to be quoted. Homogeneous vectors can appear in quasiquotations but must not contain unquote or unquote-splicing forms. I.e.,

`(,x #u8(1 2))        ; legal
`#u8(1 ,x 2)          ; illegal
