I appreciate the insight, and on closer reading the post clearly states that realistically only Zig and Rust were ever considered anyway.

Since you're here, could you comment on the approach Rust took in their rewrite? Was it more of a straight translation like Go did when they self hosted -- similar to the recent Bun transliteration? Or were there architectural changes made along the way like this article describes with Roc?

The Rust re-write happened before I got involved. If pcwalton is around and sees this comment, maybe he can provide a more first-class account.

From what I remember, it was a whole-sale re-write from scratch, not a transliteration. While Rust took a lot of inspiration from OCaml, especially in those days, it was different enough that I'm not sure that a more direct transliteration would have been particularly possible, though again, see above, I wasn't there, so I don't know for sure.
