Is WASM a good target for REPL-driven programming? I haven't studied it in detail, but I do remember that it was Harvard architecture. Would that mean that code can't be updated at runtime in real implementations?

That means that you may interactively use repl to call functions that were compiled ahead of time and to add new functions even on uncooperative targets.
After you've finished prototyping you may compile the finished library to native ahead of time.
