…r=b-naber Note user-facing types of coercion failure When coercing, for example, `Box<A>` into `Box<dyn B>`, make sure that any failure notes mention *those* specific types, rather than mentioning inner types, like "the cast from `A` to `dyn B`". I expect end-users are often confused when we skip layers of types and only mention the "innermost" part of a coercion, especially when other notes point at HIR, e.g. rust-lang#111406.

When coercing, for example,
Box<A>intoBox<dyn B>, make sure that any failure notes mention those specific types, rather than mentioning inner types, like "the cast fromAtodyn B".I expect end-users are often confused when we skip layers of types and only mention the "innermost" part of a coercion, especially when other notes point at HIR, e.g. #111406.
