error[E0393]: the type parameter `C` must be explicitly specified
--> $DIR/default-param-self-projection.rs:13:17

LL | trait A<C = <Self as D>::E> {}
| --------------------------- type parameter `C` must be specified for this
...
LL | let B: &dyn A = &();
| ^

= note: because the parameter default references `Self`, the parameter must be specified on the object type
help: set the type parameter to the desired type

LL | let B: &dyn A<C> = &();
