Namely, use a more sensical primary span. Don't pretty-print AST nodes for the diagnostic message. Why: * It's lossy (e.g., it doesn't replicate trailing `+`s in trait objects. * It's prone to leak error nodes (printed as `(/*ERROR*/)`) since the LHS can easily represent recovered code (e.g., `fn(i32?) + T`).

error[E0038]: the trait `Copy` is not dyn compatible
|
|
--> $DIR/trait-object-reference-without-parens-suggestion.rs:4:12
|

|
|
|
LL | let _: &Copy + 'static;
|
|
| ^^^^^ `Copy` is not dyn compatible
|
|
|
|
|
= note: the trait is not dyn compatible because it requires `Self: Sized`
|
|
= note: for a trait to be dyn compatible it needs to allow building a vtable
