At least this isn't a order randomization problem :-). |
This shouldn't break compatibility for crates that do not use `feature(optin_builtin_traits)`, because as the test shows, it is only possible to impl a marker trait for a trait object in the crate the marker trait is defined in, which must define `feature(optin_builtin_traits)`. Fixes rust-lang#56934
