+error[E0038]: the trait `Eq` cannot be made into an object
+  --> $DIR/object-fail.rs:7:13
+   |
+LL |     let _: &dyn EqAlias = &123;
+   |             ^^^^^^^^^^^ `Eq` cannot be made into an object
+   |
+note: for a trait to be "object safe" it needs to allow building a vtable to allow the call to be resolvable dynamically; for more information visit <https://doc.rust-lang.org/reference/items/traits.html#object-safety>
+  --> $SRC_DIR/core/src/cmp.rs:LL:COL
+   |
+   = note: the trait cannot be made into an object because it uses `Self` as a type parameter
+
+error[E0191]: the value of the associated type `Item` (from trait `Iterator`) must be specified
+  --> $DIR/object-fail.rs:9:17
+   |
+LL |     let _: &dyn IteratorAlias = &vec![123].into_iter();
+   |                 ^^^^^^^^^^^^^ help: specify the associated type: `IteratorAlias<Item = Type>`

+error: aborting due to 2 previous errors
