I really wish rust didn't make the guarantee that references are pointers, if I ever made a Rust 2.0 I wouldn't make this guarantee. It would make the `Copy` type less needed and help with extra `&&&` coming up in generics. It could make references to packed and unaligned bits safe. It could also support offset-references for self types.
