// Warning 6321: (22-26): Unnamed return variable can remain unassigned. Add an explicit return with value to all non-reverting code paths or name the variable.
// TypeError 3464: (45-46): This variable is of storage pointer type and can be accessed without prior assignment, which would lead to undefined behaviour.
