gotta remember tho that ? didn’t exist in 1.0, and now we can’t break existing code

Is that Rust's guarantee? I know that Go avoids breaking changes but I thought they were normal in Rust.

		Rust does VERY limited breaking changes, the largest one probably being the `!` type inference change that was very carefully vetted, deemed a necessity and saw contributions to fix the issue in all crates in the official registry
