Is what the author calls a C# borrow checker purely lexically based? The first error message gives that impression. And if it is, then it wouldn't qualify for any such comparisons with 2018+ Rust.

It's 100% not a borrow checker because c# doesn't have borrowing. It's just static analysis to ensure memory safety. But the author acknowledges that.

It's just checking the scopes the variables are defined in in the first example.
