I read a decent chunk of the rewrite.

It’s inaccurate to call it a rewrite. It’s more a transliteration - it matches the original Zig almost exactly but the syntax is different.

And yeah, unsafe blocks anywhere that rust would have complained

So it’s highly likely that the “rewrite” is exactly as reliable as the original.

(It sure feels like this was done for Anthropic marketing reasons, the more I think about it.)
