let mut global_reader = GlobalSectionReader::new(data, 0).unwrap();
for _ in 0..global_reader.get_count() {
    let global = global_reader.read().expect("global");

    let mut init_expr_reader = global.init_expr.get_binary_reader();
    let op = init_expr_reader.read_operator().expect("op");
    println!("Init const: {:?}", op);
}
