These are great questions!

Yes, what you're describing is the "extreme" version of LOP. Of course you don't have to do it that aggressively to get working code.

Two references I like to point to:

https://www.hashcollision.org/brainfudge/

https://beautifulracket.com/

They will give you a sense of how one uses LOP productively.

You do not need to write a "web server language"! To the contrary, the Web server provides several languages to give you a trade-off between ease and power in writing server-side Web applications. So you can just write regular Racket code and serve it through the server. The server also comes with some really neat, powerful primitives (orthogonal to LOP) — like `send/suspend` — that make it much easier to write server-based code.

Understood. Will dive deeper into Racket to get a proper understanding since it's created an itch because I still don't understand it :)

Even if I don't go fully into it as a production language, hopefully it'll open some avenues of thought that I do not yet possess.

Thank you for taking the time to respond, have a great day!
