    /// What is this : Instruct the Unity serialization backend to serialize field as a reference type, as opposed to SerializeField
    ///                 that serializes the data in place (as if it where a Value type).
    /// Motivation(s):
    ///  - Polymorphic serialization of plain old C# classes.
    ///  - Representing graph like structures without having to resort to ScriptableObjects.
    ///  - Express null fields.
