"Preserving semantics" by casting pointers to aliasing refs in Rust, ignoring lints and errors in the process.

Can't help laughing at this point.

I don't know, did the prior vibe-coded Zig code not ever have pointers aliased to data? Might be preserving semantics too well, if anything.

		The Zig one uses raw pointers. These are bad and get out of hand quickly but at least don't have constraints like "you must never have two &mut on the same value". You may refer to c2rust to see how "semantics preserving transformation" without new UBs looks like.

You didn't read the blog post at all did you? Clearly you have zero clue what you are talking about.

		Sorry, I did. And I did an internal sharing with respect to the blog post, on topics of how to (and not to) do software migration, how (not) to deal with unknown unknowns etc. We have several ongoing software (automated) migration projects so I did rather extensive research around it. I do regret that I've also read the code though, otherwise I'd probably live a little happier with ignorance right now. Sadly as they don't know they don't know about the issues, there's no indication of those in the two public materials they have released.
