code snippet to reproduce:

1. Change the package.edtion in Cargo.toml to "2021"

keyword gen is reserved beginning in the 2024 edition: https://doc.rust-lang.org/reference/keywords.html#r-lex.keywords.reserved.edition2024

2. Try the follow code

fn gen() -> usize {
    0
}

assert_eq!(gen(), 0);

ra:

expected Expr rust-analyzer [macro-error](https://rust-analyzer.github.io/book/diagnostics.html#macro-error)

Any expression whose path contains gen will trigger this bug.

struct Foo;

impl Foo {
    fn gen() -> usize {
        1
    }
}
assert_eq!(Foo::gen(), 1);

mod gen {
    fn foo() -> usize {
        1
    }
}
assert_eq!(gen::foo(), 1);
