What is the use case for this?
I have also written GUI apps for various things. Kind of like what I did with TCL back in the day.
I wrote a little maths game for my son.
I also wrote a static site generator in it that allowed me to execute racket code at compile time (interpreting each markdown file as a source file).
* A bot to reply emails that uses IMAP, SMTP and web scrapping. (It's not 100% automatic. It replies only the easy cases and adds labels so I reply the tricky ones.)
* An program to cleanup Moodle backups that uses gzip and xml. I compiled it and send it to my coworkers. (The backups have too much info, so before restoring it in another site it's better to remove the unused parts.)
Because its on top of Racket, you get usual high-level language faculties for basically free.
The education tooling is all optional (so their only impact is perceptual) DrRacket, teaching languages, and supporting libraries are all optional. (see Minimal Racket - just the compiler and package manager https://download.racket-lang.org/releases/9.0/#:~:text=SHA25... )
I'd like to know what tooling is missing from Racket that is available in major general purpose languages like C#, Java, or Common Lisp implementations?
I would love a similar tool for Racket.
You can use Typed Racket to add annotations. The compiler will verify your that your claims are consistent and perhaps add some runtime checks when you read data or use other external sources. It will remove most of the internal checks, but not all of them.
(Probably some features of Racket like impersonators make generating fast code faster, but on the other hand allows Typed Racket and other variants/libraries to ensure external objects behave correctly.)
Disclaimer: I use "Plain" Racket, so both descriptions may be slightly wrong.
