Functions

Functions are procedures (custom blocks) that can return values (or structs). Functions are always **Run without screen refresh** and must be only called within **Run without screen refresh** procedures or functions to prevent undefined behavior. Functions must always terminate with a return statement. Using `stop_this_script` inside functions is undefined behavior.

Declaring a function

func my_function(x, y) {
    return $x + $y;
}

func my_function(x, y) type_name {
    return type_name { ... };
}

Calling a function

say my_function(1, 2);
