    println!("{__func__}: log with function name");
}

#[_func_]
fn my_generic_func<T>() {
    assert_eq!(__func__, "my_generic_func");

    println!("{__func__}: log with generic function name but without generics bullshit cuz why the would I want generics in my generic name?");

#[_func_]
const fn const_func() {
    assert!(__func__.len() == "const_func".len());

async fn async_func() {
    assert_eq!(__func__, "async_func");
}
