[edg-l]

mod test_direct_use {
    mod first {
        mod second {
            struct Hello {
                a: i32,
            }

            fn hello() -> i32 {
                return 2;
            }
        }
    }

    pub fn main() -> i32 {
        let y: first::second::Hello = first::second::Hello {
            a: 2,
        };
        return y.a;
    }
}
