Is it possible for a tool invoked by info.rkt to access code which is outside
of the tool?
We’re building a #lang and would like to have on-demand syntax highlighting.
We’ve tried using a tool, and have successfully made a button and a menu item
that do it, but we’d like to activate
It's the consequence of two design goals:
1. The `module` form is separate from the `#%module-begin` syntax hook so
that the module's initial language can pick the hook macro that controls
the entire module body.
2. Racket's primitive syntax is designed so that it can be re-expanded.
I continued doing various tests and realized that my problem was something
else, since the following code works:
(module untyped-submodule racket
(provide a macro)
(define a 2)
(define-syntax-rule (macro arg) (+ 1 arg)))
Thanks for sharing.
I honed in on the review video because I like the philosophical discussions
that come from them. I'm not sure about the comments re: toxicity in the
community and how that helps one succeed in academia, but I did see some value
in discussing the merits of LOP.
Fantastic, thank you

How can I require macros coming from untyped modules into typed modules?
Intuitively I'd expect that to be possible in a way or another because such
imports don't seem to violate any safety guarantees, but maybe I'm missing

Since Redex can calculate all possible results in the judgment, Can I add
some negative premise to help derive the output? like
#:mode (infer I O)
[(infer A B)
*(not (infer number B)*
(Infer C B)]

I think this boils down to a question about how redex executes judgment
forms. Leaving aside modeless judgment forms (where redex will only check a
derivation for you but won't ever make them up), redex is turning each
judgment form into a (fancy) function from the inputs to sets of the
