Help Diagnostic For explicit lifetime name needed here

[JosephTLyons]

Using rustc 1.55.0

Given the following code: https://play.rust-lang.org/?version=stable&mode=debug&edition=2018&gist=deaf96d3f30f20986ce469e1b49664ff

use std::iter::Sum;

fn main() {
    println!("Hello, world!");
}

fn add<T: 'static + Sum<&T>>(values: &[T]) -> T {
    values.iter().sum()
}

The current output is:

❯ cargo run
   Compiling lifetimes v0.1.0 (/Users/josephlyons/Desktop/lifetimes)
error[E0637]: `&` without an explicit lifetime name cannot be used here
  --> src/main.rs:52:25
   |
52 | fn add<T: 'static + Sum<&T>>(values: &[T]) -> T {
   |                         ^ explicit lifetime name needed here

error[E0621]: explicit lifetime required in the type of `values`
  --> src/main.rs:53:19
   |
53 |     values.iter().sum()
   |                   ^^^ lifetime `'static` required

Some errors have detailed explanations: E0621, E0637.
For more information about an error, try `rustc --explain E0621`.
error: could not compile `lifetimes` due to 2 previous errors

Not sure what the proposed output would be, but some sort of help / suggestion could help to make this easier for beginners

In addition, "error[E0637]: & without an explicit lifetime name cannot be used here" does not look like the right error here. The playground links to E0637, which is specifically about _ used as a lifetime identifier.
