Description
Summary
#[allow(clippy::redundant_closure)] that worked until Rust 1.81 seems to have broken in Rust 1.82. Specifically, clippy::redundant_closure can no longer be suppressed with #[allow(...)] in Rust 1.82 (I haven't tested whether subsequent Rust versions exhibit the same issue).
Reproducer
I tried this code:
// src/main.rs
#[allow(dead_code)]
struct Foo(i32);
impl Foo {
fn new(i: i32) -> Self {
Self(i)
}
}
fn main() {
let i = Some(1);
let _f = i.map(
#[allow(clippy::redundant_closure)]
|i| Foo::new(i),
);
}I expected no warning from cargo clippy (which is the case for Rust 1.81)
$ cargo clippy

Instead, this happened:
$ cargo clippy
warning: redundant closure
--> src/main.rs:13:9

13 | |i| Foo::new(i),
| ^^^^^^^^^^^^^^^ help: replace the closure with the function itself: `Foo::new`
