Here's what I would do: - Add `(provide (all-defined-out))` at the top of the file (or in a #lang elixir) - Have `(define ...)` just be the regular racket define. - Have `(definep f e)` work like this:
(define f* e) (define-syntax f (make-rename-transformer (syntax-property #'f* 'not-provide-all-defined-out #t))) That way you can't reference f* anywhere, so it's private, and `f` is not automatically provided. Of course, you can still explicitly provide `f` if you want.
