  This definition of "perfect" might be counterintuitive for those that haven't read the piece. The idea is there might some ideal memory allocation scenario that Rust doesn't do "perfectly" that you can theoretically do better in Zig, which I buy. Most particularly, my experience with arenas and defer drop is -- they aren't always perfectly easy in Rust. But this definition of perfection tends to ignore all the manual, boilerplate memory management you have to do in the interim, that you may still mess up in some subtle way.

That is my experience also: https://blog.reverberate.org/2021/12/19/arenas-and-rust.html https://blog.reverberate.org/2021/12/19/arenas-and-rust.html I was hoping the borrow checker would perfectly check arena lifetimes. And it does, but it requires that your types have lifetime parameters. That makes logical sense, but my experience attempting to actually use a type with a lifetime parameter is that it is so painful as to not be practical in a low-level library.

      "Why is Rust’s 'Bump' not' Sync'?" was exactly the issue I was thinking of. Thanks for writing this. Seriously, a must read!
