Suggests to initialize struct with private fields, instead of looking for typo

I typo’d `handle` (local variable) with `Handle` (type with private fields I have no access to). Would have expected rustc to not emit such a note and maybe look for typos instead.

```
error[E0423]: expected value, found struct `Handle`
   |
73 |                     handle: Handle,
   |                             ^^^^^^ did you mean `Handle { /* fields */ }`?
```
