Nice, but what are the non goals?

Except maybe the compilation to native binary, this is closer to clojurescript than clojure I suppose ?

How about a comparison with Jank?

I'm working on something similar.

My guess is, within the next 3-5 years, most ALGOL descendant languages will become obsolete, and S-exp based Lisp dialects will take over. Objectively superior.

Behold a native kernel, no inline asm or linker scripts, of any kind. The full compiler pipeline is controllable through the compiler (you can arbitrarily target, devise, or enable/disable various optimization passes, for instance you can enable LICM at will). Also has a hard 1:1 correspondence to C/C++/Rust/adding more languages soon.

Why not name it “Cloju.rs” instead? :-)

Cool.

I'm already a big fan of the scheme-rs crate.

I use it any time I need a dynamic scripting language.

It allows for more flexible hot-reloading of parts of a program.

I don't personally have any Clojure interop holes that need filling.

But I can imagine a future where one moves partially away from the JVM if e.g. faster starts or leaner container images are desired.
