I'm not aware that anybody on the Forth-200x committee knows what quotations are, much less how to implement them. I suggested to Elizabeth Rather that the next time she is teaching her novice class, she ask her students to explain the concept to her --- I assume that all of her students are familiar with basic concepts such as this.

Example of a closure in Racket (Scheme):


(let ((multiplier 800))
  (for-each
    ;; The closure.
    (lambda (n) (displayln (list n (* n multiplier))))
    '(1 1 2 3 5 8 13 21)))
