alt Hacker NewsA concern with these LLM-driven rewrites is that the Rust code isn't really idiomatic, it ends up being C++ code in a trench coat (raw pointers everywhere, manual validation of thousands of unsafe blocks). So far every publicized rewrite I'm aware of has had an "oh and we'll definitely spend the thousands of hours needed to fundamentally rework the code to properly utilize lifetimes later" admission tacked on at the end. Has there been progress in improving that aspect during the LLM phase of the rewrite? If so that would be an incredible win for the industry!

I'd say so! We aim to have our replacements to be `forbid(unsafe)` - no raw pointers - outside of `ffi.rs`. Of course it's tricky because we need to interoperate with existing C code, but we've been trying to come up with abstractions that make this a bit more ergonomic (https://github.com/google/safer_cffi).
