rust-analyzer version: rust-analyzer version: 0.4.2822-standalone (e0269ce 2026-03-10)

rustc version: rustc 1.96.0-nightly (e370b60cf 2026-03-07)

editor or extension: VS Code 1.112.0; rust-analyzer extension 0.4.2822;

relevant settings: N/A

code snippet to reproduce:
crate a, src/lib.rs:

#![feature(decl_macro)]

pub macro inner() {
    true
}

pub macro outer() {{
    fn __check() -> bool {
        inner!()
    }
    true
}}

crate b, src/main.rs:

use a::outer;

fn main() {
    outer!();
}

Expected: No error. cargo +nightly build compiles.
Actual behavior:

expected bool, found ()

We don't implement macro 2.0 hygiene.
