That’s why I found GraalVM’s approach intriguing. They provide a high level language API where you can simply write a language interpreter, and it will be able to JIT/AOT compile it down to fast machine code. But the most interesting aspect is that the IR they convert languages to is basically universal, so something like LLVM bitcode can also use the exact same representations. So you can interpret (and later AOT compile as well) LLVM bitcode and python, and this approach will allow cross-language optimizations as well, which were not available at all before. But feel free to add a bit of JS/Java, etc to your code as well!
