Error message for inferred lifetime failure isn't great

[jdm]

This code does not work:

use std::borrow::Borrow;

struct S;
trait T {}
impl T for S {}

impl Borrow<T> for S {
    fn borrow(&self) -> &T {
        self as &T
    }
}

fn main() {
    let s = S;
    let _t: &T = s.borrow();
}

The error message I get is:

error[E0495]: cannot infer an appropriate lifetime for lifetime parameter in generic type due to conflicting requirements

error: aborting due to previous error

This code does work:

use std::borrow::Borrow;

struct S;
trait T {}
impl T for S {}

impl<'a> Borrow<T + 'a> for S {
    fn borrow(&self) -> &(T + 'a) {
        self as &T
    }
}

fn main() {
    let s = S;
    let _t: &T = s.borrow();
}

The only clue I got was this note:

note: ...so that method type is compatible with trait (expected fn(&S) -> &T + 'static, found fn(&S) -> &T)

which even then I wasn't clear if my change would make a difference or not. Is there some change we could make to the output that would make the solution clearer?

Triage: no change other than &T -> &dyn T.
