I understand your comment was tongue-in-cheek, but we certainly have an interest in cross-language interoperability! You can check out our work here:

- https://try.gambitscheme.org is Gambit compiled to JavaScript with the universal backend. Evaluate \alert("hello!") at the REPL to see the JS<->Scheme Syntactic FFI in action.

- https://codeboot.org is our own Python interpreter running in the browser. It has a Python<->JS FFI. Evaluate \alert("hello!") at the REPL to test it out. You can even import JS libraries using the standard Python syntax by replacing the identifier with a string: import "https://mycdn.com/mylibrary.js".

- https://github.com/gambit/python is a Gambit module that integrates Gambit with CPython, using the same syntactic FFI. You can import PyPI modules from Gambit.

References to conferences/papers describing these features can be found on my GH profile (https://github.com/belmarca). AMA if you wish!

I used it a long long time ago on one of my first freelance gigs (with a PHP target). It was already quite solid and saved me the need to use a PHP framework.

I also remember using it as a typed javascript pre-compiler, at a time where FB Flow and MS Typescript were still fighting over developer mindshare. I would probably still use it if TS didn't take over the ecosystem entirely.
