error[E0038]: the trait `Trait` cannot be made into an object
--> $DIR/E0038.rs:5:20

LL | fn call_foo(x: Box<dyn Trait>) {
| ^^^^^^^^^ `Trait` 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>

LL | trait Trait {
| ----- this trait cannot be made into an object...
LL | fn foo(&self) -> Self;
| ^^^^ ...because method `foo` references the `Self` type in its return type
= help: consider moving `foo` to another trait
error: aborting due to previous error
