Josh Stone e67e165585 Make ThinBox<T> covariant in T ... Just like `Box<T>`, we want `ThinBox<T>` to be covariant in `T`, but the projection in `WithHeader<<T as Pointee>::Metadata>` was making it invariant. This is now hidden as `WithOpaqueHeader`, which we type-cast whenever the real `WithHeader<H>` type is needed.		2022-06-27 10:05:55 -07:00
