The article is presenting a Scheme interpreter running in Scheme, compiled to WASM, not a Scheme compiler, but your idea is also cool. The WASM API apparently doesn't need a pre-made file as its input: you can pass raw bytes generated during runtime into the Module constructor, so it would be totally feasible.

When we have the compiler running in Wasm we'll post about that, too. That's the dream.
