Interesting project. Have you considered making an REPL using WASM in browsers as a playground?
I am developing this music live coding language and audio library with Rust and it runs in browsers:
I am now using Rhai.rs as the embedding language to write `meta' node in the audio graph. But for audio programming, the running time for each block should not exceed 3ms. In some cases, I found Rhai quite struggling with that. Perhaps dynamic languages have an inherit limitation on that? Wondering how do you see this issue and will performance be part of the future consideration of sphinx-lang?
