Ideally something with a C-FFI interface and a runtime without a lot of concurrency opinions. Hooking up Python and Pony is fairly straightforward for example.

Ideally something with a C-FFI interface and a runtime without a lot of concurrency opinions. Hooking up Python and Pony is fairly straightforward for example. We've done it at Wallaroo Labs. That's very much "embedded a Python interpreter inside a Pony process" approach. Perhaps you are thinking of something different? I'm not really sure what you are thinking of. If you sent your ideas to the user mailing list, someone might have some ideas. Something a bit more concrete might help on that front.
