Invalid `?` suggestion on mismatched `Ok(T)`

[eopb]

Code

pub fn foo() -> Result<String, ()> {
    let out: Result<(), ()> = Ok(());
    out
}

Current output

Compiling playground v0.0.1 (/playground)
error[E0308]: mismatched types
 --> src/lib.rs:3:5
  |
1 | pub fn foo() -> Result<String, ()> {
  |                 ------------------ expected `Result<String, ()>` because of return type
2 |     let out: Result<(), ()> = Ok(());
3 |     out
  |     ^^^ expected `Result<String, ()>`, found `Result<(), ()>`
  |
  = note: expected enum `Result<String, _>`
             found enum `Result<(), _>`
help: use `?` to coerce and return an appropriate `Err`, and wrap the resulting value in `Ok` so the expression remains of type `Result`

3 |     Ok(out?)
