error: this `Deref` implementation is covered by an implicit supertrait coercion
--> $DIR/migrate-lint-deny-regions.rs:8:1

LL | impl<'a> Deref for dyn Foo<'a> {

...
LL | type Target = dyn Bar<'a>;
| -------------------------- target type is a supertrait of `dyn Foo<'_>`

= warning: this will change its meaning in a future release!
