Invalid just add parentheses suggestion for closure doesn't impl trait #145404
Description
Code
use std::fmt::Display; struct S; impl S { fn call(&self, _: impl Display) {} } fn main() { S.call(|| "hello"); }Current output
error[E0277]: `{closure@src/main.rs:9:12: 9:14}` doesn't implement `std::fmt::Display` --> src/main.rs:9:12 | 9 | S.call(|| "hello"); | ---- ^^^^^^^^^^ the trait `std::fmt::Display` is not implemented for closure `{closure@src/main.rs:9:12: 9:14}` | | | required by a bound introduced by this call | note: required by a bound in `S::call` --> src/main.rs:5:28 | 5 | fn call(&self, _: impl Display) {} | ^^^^^^^ required by this bound in `S::call` help: use parentheses to call this closure | 9 | S.call(|| "hello"()); | ++Desired output
9 | S.call((|| "hello")());Rationale and extra context
The suggestion doesn't compile because it fails to take account of precedence.
