Good question — I’m not 100% sure. I'm not an expert on Ruby or JS internals, and I haven’t studied their execution models deeply. But in theory, if the language is stack-based (or can be mapped cleanly onto a stack machine), and if the ISA is broad enough to cover their needs, it could be possible. Right now, PyXL’s ISA is tuned around Python’s patterns — but generalizing it for other languages would definitely be an interesting challenge.
