A couple of others that may be of interest:

- https://ferret-lang.org/ "Ferret is a free software lisp implementation designed to be used in real time embedded control systems. Ferret lisp compiles down to self contained C++11" "Easy FFI (Inline C,C++. See Accessing C,C++ Libraries)" "Easily Embeddable (i.e Ferret fns are just C++ functors.)"

- https://github.com/clasp-developers/clasp "Clasp is a new Common Lisp implementation that seamlessly interoperates with C++ libraries and programs using LLVM for compilation to native code."

Not trying to be a Lisp gatekeeper, I just want to give credit since Common Lisp is such a gigantic standard:

Embeddable Common Lisp is a conforming implementation. It's what it says in the title, pretty much any Common Lisp library and still embeddable in C/C++. Use it with SLIME and all that.

I do like exo-lisps like Fennel, Ferret and Hy. They just have very different goals from the project referenced in this article.

Plug: for fun I made a (less ambitious) version of this kind of thing for Rust which I ended up being pretty happy with

Cool post :)

I'm one of ECL maintainers, if you have questions about the implementation itself then I'll be happy to answer.

I thought guile was specifically designed for embedding, like lua. And, isn't it JITted nowadays?
