| LL | fn foo(x: &dyn BB) {} |
| | ^^ `BB` is not dyn compatible |
| | |
| note: for a trait to be dyn compatible it needs to allow building a vtable |

| LL | trait BB = Bar<{ 2 + 1 }>; |
| | -- ^^^^^^^^^^^^^^ ...because it uses `Self` as a type parameter |
| | | |
| | this trait is not dyn compatible... |
| help: consider using an opaque type instead |
