There's at least one other Rust implementation of lox that I know of (https://github.com/tdp2110/crafting-interpreters-rs) (no unsafe)
It's always interesting to see how different people approach the problems in their own language or relative isolation. I agree with others here, the real value of the original work lies in avoiding copy and paste.

I've also found the exercise of implementing Lox in another language as highly instructive in learning how to write idiomatic code in that language. I continue to learn more about the best way to express patterns as I work on my own implementation. I'd recommend the journey to any professional developer for this side-benefit alone.

Though there's probably a similar claim to be made for the Monkey-language from Torsten Bell, via his books on compilers and interpreters.
Maybe! It's definitely getting there. I suspect "semi-arbitrary subset of C" still has me beat but who knows for how much longer.
On a more serious note, have you thought about trying to aim lightning at the same spot again and write another book about implementing something most programmers take for granted?
Just want to hopefully make you feel warm inside knowing you've made a really big difference to people's lives
Thanks for being you
