This PR appears to be over a million lines (though GitHub won't load for me).

Of course the quality is the real question. I haven't had amazing results with LLMs with Rust, but they're less bad at it than they are at Zig, which is probably the reason for the rewrite.

At least in this case the original code was written carefully by hand, so the design is sane, and now just the auto-translation is in question. Now it just needs to be battle tested.

Bun is now literally vibe-coded, that's your proof. And Bun developers will solely use LLMs at some point (pretty close to "vibe coding").

Bun is now the example. It's >1million lines of code, entirely vibe coded. All we do now is wait and see what happens.
