Kind2 VS macro-lisp

Agreed. Even from a PLT perspective, I prefer Kind2 by the Kindelia Foundation for supporting inductive theorem proving (and hopefully some level of dependent types), as well as being faster to boot.

I agree. Keep in mind our language (Kind-Lang) does target the HVM, and it is really promising. The type-checker is the fastest among proof assistants, by far; the error messages are really nice; it has a fully dependent type system which is a breath of fresh air to work with. It is still not production ready though (mostly due to lack of IO), but is the extend of our effort on that direction. We hope other lang developers get encouraged to target the HVM to. Elm and Idris are great candidates for that IMO.

Another very small proof system: https://github.com/moonad/formcorejs

The core implementation is under 700 lines of JS, including the parser: https://github.com/moonad/FormCoreJS/blob/master/FormCore.js

The author has since moved on to building a runtime with optimal evaluation (https://github.com/kindelia/hvm) and a new proof language on top of that (https://github.com/Kindelia/Kind2) with considerably better performance than existing proof systems.

Rust’s macro system is safe and hygienic, people have implemented lisps in it. I just did a google search to find an example, so I have no idea how well supported this is, https://github.com/JunSuzukiJapan/macro-lisp

You can already have both: https://github.com/JunSuzukiJapan/macro-lisp

Via a lisp macro?

Rust macros can make the language look like anything, even lisp: https://github.com/JunSuzukiJapan/macro-lisp

Why not get the best (?) of both worlds with the macro-lisp crate: https://github.com/JunSuzukiJapan/macro-lisp

A small snippet from the project's examples shows minimal boilerplate between Rust and a native-looking Lisp experience:

After that, I'm going to go back to working on adding some scripting. My attempts at making a Lisp in Rust failed spectacularly, but when trying to find a ready made replacement that's not too big (so not RustPython and not Rhai or Dyon) I found mentions of DSL, which are usually Rust macros, which led me to https://github.com/JunSuzukiJapan/macro-lisp (single file, circa 400 lines, that does basically the whole job I want, i.e. being able to call Rust functions when I need them, e.g. from an in-game console)
