    let p = Point { x: 3, y: 0 };

        Point { x: 0, y } => println!("on the y axis at {}", y),
        Point { x, y } => println!("at {},{}", x, y),
    }

    let n = 15;
    let kind = match n {
        x if x % 15 == 0 => "fizzbuzz",
        x if x % 3 == 0 => "fizz",
        _ => "other",
    };
    println!("{}", kind);
}

got 7
popped 3
popped 2
popped 1
on the x axis at 3
fizzbuzz
