;; Eli: If this ever gets in, it should say that the memory requirements
;;   are 4 times the input size, especially since bytes are often used to save
;;   space.  Also, fails on (bytes-ci=? #"\277" #"\277"), and a trivial fix
;;   would still fail on (bytes-ci=? #"\276\277" #"\277\276")

;; Eli: This is a really bad name for something that is often called
;;   `read-from-string', or `read-from-bytes' in this case.  I first read it as
;;   "read with bytes".  Regardless, I see little point in composing two
;;   functions where the two names are clear enough -- you might consider
;;   looking at the version in CL.

(define (write/bytes v)
  (define by (open-output-bytes))
  (write v by)

;; Eli: Same bad name as above.  Also, is there any point in this given
;;   (format "~s" v), and the fact that using the resulting string for printout
;;   will get the same result.
