alt Hacker NewsNo one involved in the port proposed "blindly porting Zig code 1:1 and calling it a day". From the first blog post the creator said:

What the rewrite does is make the unsafe code greppable, which is a necessary first step to eliminating it and one that's actually achievable rather than going straight to idiomatic.
Every successful refractor takes this form of stepwise changes that leave the behavior intact. It just so happens that in this case the first stepwise change was the implementation language.
> We can gradually refactor it
Is quite a hell of a statement, when memory management issues are highly nonlocal and need some careful design upfront in order for you to nail it.
Unsafe isn't something that you can gradually clean up. Even one single flawed usage of unsafe (an ill-assumed invariant) can poison the whole program in scary ways, and might require a total refactor of your codebase to fix it.
