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) [1]: https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=7f8b6f4433aa7866124123575456f54e Signed-off-by: Sasha Pourcelot <sasha.pourcelot@protonmail.com>
