Multi Line Arm

The arm of a match expression can contain multiple lines of code by wrapping the right side of the arrow => in brackets {}.

    let number = 5;

    let result = match number {
        0 => {
            // Multiple lines of code here then return 10
            10
        },
        1 => 20,
        5 => 50,
        catch_all => 0,
    };
