I think it would be nice to take a step back and think about what you really want to do. Who will be the users of this library? How will the library be used? Do you intend that regular Racket programs are able to require your library, or is it in its own ecosystem entirely?
From a quick glance, it looks like you are circumventing the module system and hygienic macro system, and using reflection liberally. Those are things that regular Racket programs would not do, unless there is a really good justification. I wouldn’t be surprised if right now Racket programs can’t interop well with the library.
