Oh, cool! SmithForth[0] is how I originally learned about x86-64 microarchitecture. It's a Forth that bootstraps off hand-coded x86-64 opcodes. I decided to go the other direction and decompile the binary by hand. It really is a beautiful piece of code. Highly recommended reading.
Also, you're excited by Forth and Lisp, you might like Forsp[1]. It uses a call-by-push-value evaluation strategy in a way that really makes the language feel like a true hybrid of the two. The implementation is also brilliantly simple.
Anyway, thank you for the article. I lurk on the DuskOS mailing list and wish I could find out where the Forthers gather IRL so I could osmote more of their world into my own.
I’ve started thinking of concatenative languages as “backwards lisps” in my head and so far it seems like a reasonable take.
