Ah, I see! Yeah that's significantly trickier.

re: "dynamically replace parts of the implementation as source code evolves" — there is a technique for this, I have a short write-up on it here: https://github.com/pdubroy/til/blob/main/wasm/2024-02-22-Run...

About the debugging and inspecting —

Inspecting Wasm memory is easy from JS, but to be able to do the debugging, you'd probably either need to rewrite the bytecode (e.g., inserting a call out to JS between every "real" instruction) or a self-hosted interpreter like wasm3 (https://github.com/wasm3/wasm3).

(Or maybe there are better solutions that I'm not thinking of.)
