7GUI VS racket-binfmt

Looks like you're already in Emacs. I strongly recommend racket-mode as mentioned in another thread.

With regard to prototyping GUI's I'd suggest taking a look at https://github.com/mfelleisen/7GUI. https://github.com/Bogdanp/racket-gui-easy could also be a good place to start.

With regard to Racket more generally, I'm probably not the best person to ask since I had a very high friction start where I just banged my head against the wall until things made sense.

Some simple examples using the Racket gui toolkit can be found at https://github.com/mfelleisen/7GUI

Racket has a nice gui that works across windows, Linux and MacOS, See https://github.com/mfelleisen/7GUI

Racket internalizes Extra-linguistic mechanisms https://felleisen.org/matthias/manifesto/sec_intern.html

Also the fact that various DSLs can inter-op with each other directly, so that you can use something like a binary parser description, as if it was just another Racket library. For example this description of the format https://github.com/Bogdanp/racket-binfmt/blob/master/binfmt-..., is directly included in another file as a regular library https://github.com/Bogdanp/racket-binfmt/blob/master/binfmt-...

I agree that startup time is not a winning aspect of Racket. My naive understanding is because Racket is not a direct bytecode interpreter like CPython, but actually has to run a compile step to native code, and doing that for programs + their required libraries necessarily takes at least a couple of hundred milliseconds even before anything can start running, while CPython can pretty much start executing from the get go.
