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.

[–] Giooschi -1 points 4 weeks ago

It's a very different kind of borrow checking than Rust's. For example there's no mutability xor sharing checking, because mutability cannot invalidate memory (there's still a GC in C# after all!). As such, Rust's NLL (which are available in the 2015 edition too btw) don't really make sense in C#.
