> Seasoned Rust coders don’t spend time fighting the borrow checker...

Experienced Rust coders aren't going to find themselves in various borrow checker (and lifetime) pitfalls that newbies do, sure.

That said, the borrow checker and lifetime do cause problems for even experienced Rust programmers. Not because they don't understand memory management, lifetimes, etc. But because they don't - yet - fully understand the problem being solved.

All programs are an evolutionary process of developing a solution to a problem (or many problems). You think one thing, code it up, realize you missed something or didn't fully grok the issue, pivot, etc.

Rust does a great job in the compiler of letting the user know if they've borked something. But often times a refactor/fix in C/D/Zig due to learned (or new) requirements is just a tweak, while in Rust it becomes a major overhaul because now something needs to be `mut` or have a lifetime added to it. I - personally - consider that "fighting" the borrow checker, regardless of how helpful (or correct) it also is.
