; (listq object ...)  ==>  list
;
; LISTQ is like LIST, but quotes each OBJECT passed to it.
; Rationale: (list a b c)    evaluates a, b, and c
;            '(a b c)        makes the list immutable
;            `(a b c)        may be inefficient
;            (list 'a 'b 'c) is awkward
;
; Example:   (listq a (b c) d)  ==>  (a (b c) d)
