Interesting - does the default #%top-interaction behave differently from
#%module-begin w.r.t. to a #lang's read?
Right now my main.rkt is providing the standard #%module-begin,
#%top-interaction, #%app, #%datum, and #%top, in addition to my language's
functions + macros.
Thanks!
On Fri,
There may be other solutions, but one way to control the evaluation of
expressions entered in the REPL
is to provide an #%top-interaction, which sets the appropriate parameters.

Quick follow-up:
It looks like I may somehow be able to change DrRacket's printing and
reading behavior on a per-language basis somehow using the classes here

This sounds like a good lead - curious if this also applies to `write` and
`display` as
DrRacket uses `pretty-print`, which will print numbers using
`number->string`, and so (I think) won't go through your parameter.
I think there may be problems with parametering the core printer,
partly because printing is is sometimes used where `read` is supposed
to work on the result, but I
