Why is it hard? Isn't wasm designed so you can statically and quickly compile pieces of it or the whole thing to native code, rather than needing to do all the tricks dynamic language runtimes do?
That is their very nice slogan, while in reality WASM still has quite a way to go to compete with native code.
Some shits I see these days are that when code speed is measured, people compare that with JS but not native code, when portability is talked about, the comparison is then made against native code, not JS.
