warning[E0210]: type parameter `T` must be covered by another type when it appears before the first local type (`B`)
--> $DIR/orphan-check-alias.rs:21:6

LL | impl<T> foreign::Trait2<B, T> for <T as Id>::Assoc {
| ^ type parameter `T` must be covered by another type when it appears before the first local type (`B`)

= warning: this was previously accepted by the compiler but is being phased out; it will become a hard error in a future release!
= note: for more information, see issue #124559 <https://github.com/rust-lang/rust/issues/124559>
= note: implementing a foreign trait is only possible if at least one of the types for which it is implemented is local, and no uncovered type parameters appear before that first local type
= note: in this case, 'before' refers to the following order: `impl<..> ForeignTrait<T1, ..., Tn> for T0`, where `T0` is the first and `Tn` is the last
= note: `#[warn(uncovered_param_in_projection)]` (part of `#[warn(future_incompatible)]`) on by default
warning: 1 warning emitted
