I am running the silly program below (no meaning), and on occasion I see the
output of the *** line in the console from where I launched drracket. 5.2.0.1
from 10/16
#lang racket
(require (for-syntax syntax/parse))
(define-for-syntax (postfix stx word stem)
(datum->syntax stx (string->symbol (string-append word "-" (symbol->string
stem)))))
(define-syntax (define-un-serialize stx)
(syntax-parse stx
[(_ name:id (argument:id ...) unparser:expr parser:expr)
(define serialize (postfix stx "serialize" (syntax-e #'name)))
(define deserialize (postfix stx "deserialize" (syntax-e #'name)))
(displayln `(,serialize ,deserialize)) ;; ****
#`(define-values (#,serialize #,deserialize)
(values (lambda (argument ...) unparser)
(lambda (msg) parser)))]))
(define-un-serialize f (x y) values values)
