async func support

[QuarkContainer]

Can this support the async func? for example

use label::create_label;

create_label!(async fn test() -> ());

#[test::label] async fn my_fn() { println!("Test!"); }

fn main() { println!("calling all 'test' label"); // using iter you can go through all functions with this annotation. for i in test::iter() { i().await; } }
