I verified that the pre-release version 7.4.0.902 resolves my issue with
~between. With that fix I was able to complete the macro I was working on.
Thanks again for the advice and the quick response by the Racket dev team!

I just wanted to follow up to say that I finally got this working! I
finally re-implemented all of my non-hygienic macros with syntax-parse,
which resolved the unbound identifiers.
Once again, thanks to everyone who offered help and suggestions.

I feel like I might not understand what you want, but it feels like
you just want to use `make-module-evaluator` from `racket/sandbox`:
```
#lang racket/base
(require racket/sandbox)
(define (read-script s)
(((make-module-evaluator s) 'script) 5))
(module+ test
(read-script

Hey Eric! Thanks, I'll try to soak in this a bit tomorrow. :)

This works:
1. mkdir foo; cd foo; raco pkg install
2. create foo/main.rkt:
```
#lang racket/base
(module reader racket/base
(require racket/port)
(provide (rename-out [foo-read read]
[foo-read-syntax read-syntax]))
(define (foo-read port)
`(module ,(gensym 'foo)
When I run
```
#lang racket/load
(module p racket/base
(define out (make-parameter 'original-value))
(provide out))
(module a racket/base
(require 'p)
(displayln (list 'a (out)))
(define a 43)
(provide a))
(require 'p)
(displayln (list 'outer (out)))
(out "foo")

Well, I think I figured out how to get further:
with example1.rkt being:
```
#lang racket/base
;; #lang dungeon/misery
(define ((make-start-game read-save-file) player-name)
(list 'running-this-read-save-file: read-save-file
'on-player-name: player-name
'result: (read-save-file
Thanks, that's helpful. I'll probably take the same route as you with a
build.rkt; it would be nice to have everything self-contained and not
depend on platform-specific shell scripts or another language.

Background: the gregor date and time library depends on another
library called tzinfo to provide information from the systems zoneinfo
database. However, not all systems have a zoneinfo database installed
(notably, Windows systems, but also some minimal UNIX ones used in
Docker containers, for exam
Hi Eric! Thanks very much for the reply.

I have no experience with Redex (it is one of the things I want to get more
familiar with in the future), but I happened to watch this talk:

Hi All,
How can I set a parameter used in a dynamically required module?
Example:
A parameter `out` is defined in a module p.
Before requiring (dynamically) module a, we want to set the parameter.
The attempt below fails.
(module p racket/base (define out (make-parameter 'original-value))
(
Thanks Jay for the helpful response as usual Jay; I really do appreciate
it.
It sounds like what I want is the case of the export. I think I can
figure out how to modify the #%module-begin to do that.
I guess a question remaining then is: if I'm doing this kind of dynamic
import of the module, i
