diagnostics for E404 suggests use which already exists

[jendrikw]

(A better title would be appreciated)

Code

use std::io::Read;

fn f<T: Read, U, Read>() {}

Current output

Compiling playground v0.0.1 (/playground)
error[E0404]: expected trait, found type parameter `Read`
 --> src/lib.rs:3:9

help: consider importing one of these items instead

  |

Desired output

I like this part:

 --> src/lib.rs:3:9
  |
1 | use std::io::Read;
  |              ---- you might have meant to refer to this trait
2 |
3 | fn f<T: Read, U, Read>() {}
  |         ^^^^     ---- found this type parameter
  |         |
  |         not a trait

It could have a suggestion like did you mean : instead of ,, especially because ,<.>;: are very close to each other on a US keyboard and could very well be a typo.

Rationale and extra context

Applying the suggestion use std::io::Read will result in a compile error.

I think the label D-invalid-suggestion might be fitting as well.
