warning: this `Deref` implementation is covered by an implicit supertrait coercion
--> $DIR/migrate-lint-different-substs.rs:11:1

LL | impl<'a> Deref for dyn Foo + 'a {
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ `dyn Foo` implements `Deref<Target = dyn Bar<u32>>` which conflicts with supertrait `Bar<i32>`
...
LL | type Target = dyn Bar<u32> + 'a;
| -------------------------------- target type is a supertrait of `dyn Foo`

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