What lang ecosystem with an interactive REPL do you see as the best fit for pairing with and driving Pony? I've been dreaming of ways to help bootstrap the Pony lang/lib interop story and build toward a numerical interactive programming environment, being able to combine Pony's native async Actor model and runtime safety guarantees, while also safely being able to hook into to an external ecosystems existing numerical computing, data structure, and GPU/TPU accelerator libs. I seem to remember someone giving a lang talk a while back where in the Q&A the speaker said integrating with Pony might be a good fit. I was looking into dependent types at the time...it may have been Idris or OCaml, and hooking into the Julia ecosystem would be most interesting, with maybe even Zig acting like low-level LLVM glue code binding all the external C libs together. In my dream I have it all and the Pony too! All the lang libs are hooked together in a typed-provable way, and when fully connected they combine to form a high-performance, interactive parallel distributed programming environment, and it runs in the browser too. What do you think, is that too much of a DeepDream?
