If I have a syntax extension that expands to include "define" and/or
"provide/contract" (at top level, possibly within a "begin"), will that
break any Racket tools?
The "myprogram.rkt" below works, but I don't know whether this will
break some tool now or in the future.
#lang racket/base
;; File: foo.rkt
(require racket/contract)
(define-syntax foo-define/provide/contract/begin
(syntax-rules ()
((_ SYM CONTRACT BODY0 BODYn ...)
(begin (display "*DEBUG* before\n")
(define SYM BODY0 BODYn ...)
(provide/contract (SYM CONTRACT))
(display "*DEBUG* after\n")))))
(provide foo-define/provide/contract/begin)
#lang racket/base
;; File: mymodule.rkt
(require "foo.rkt")
(foo-define/provide/contract/begin onetwothree number? 123)
#lang racket/base
;; File: myprogram.rkt
(require "mymodule.rkt")
(printf "onetwothree is ~S\n" onetwothree)
