Incorrect error order for println!

[pickfire]

I tried this code:

fn main() {
    let guess = "123";
    let guess = match guess.trim().parse() {
        Ok(num) => num + 1,
        Err(_) => todo!(),
    };
    println!("guess: {}", guess);
}

I expected to see this happen:

  |
4 |         Ok(num) => num + 1,
  |            ^^^ cannot infer type
  |
help: consider specifying the type argument in the method call
  |
3 |     let guess = match guess.trim().parse::<F>() {
  |                                         ^^^^^

Instead, this happened:

  |
7 |     println!("guess: {}", guess);
  |                           ^^^^^ `()` cannot be formatted with the default formatter
  |
  = help: the trait `std::fmt::Display` is not implemented for `()`
  = note: in format strings you may be able to use `{:?}` (or {:#?} for pretty-print) instead
  = note: required by `std::fmt::Display::fmt`
  = note: this error originates in a macro (in Nightly builds, run with -Z macro-backtrace for more info)

But eventually I will be able to see that once I use {:?} but users need to do an extra step to see the other warning.
