Wasm is explicitly not designed for interpretation (https://arxiv.org/abs/2205.01183)
replyWasm is definitely designed to be compiled, either ahead of time or JITed. Wasm interpreters are few and far between.
replyHuh you're right. I had worked with interpreted WASM before, which is why I thought that was more common.
replyWASM is a great system, but quite complex -- the spec for Mog is roughly 100x smaller.
