The current message for "`->` used for field access" is the following:
```rust
error: expected one of `!`, `.`, `::`, `;`, `?`, `{`, `}`, or an operator, found `->`
--> src/main.rs:2:6
|
2 | a->b;
| ^^ expected one of 8 possible tokens
```
(playground link[1])
This PR tries to address this by adding a dedicated error message and recovery. The proposed error message is:
```
error: `->` used for field access or method call
--> ./tiny_test.rs:2:6
|
2 | a->b;
| ^^ help: try using `.` instead
|
= help: the `.` operator will dereference the value if needed
```
(feel free to bikeshed it as much as necessary)
