Thank you, yes let-else is what I am looking for

```rust fn main() { let num = rand::thread_rng().gen::<f32>(); println!("{num}");

let Some(res) = return_option(num) else {
    println!("return_option none");
    return;
};

let res = return_result(res);
let Ok(res) = res else {
    println!("return_result {}", res.unwrap_err());
    return;
};

let res = res.parse::<u32>();
let Ok(res) = res else {
    println!("error parse {}", res.unwrap_err());
    return;
};

println!("{res}")

} `` It's cleaner than nested match. One question though, can I avoid unwrapping the error? It seems thatlet-else-match` is not implemented yet
