    The traits package from the Enthought Tool Suite provides a
    metaclass with special attributes that are called traits. A trait
    is a type definition that can be used for normal Python object
    attributes, giving the attributes some additional characteristics:
    * Initialization: A trait attribute can have a default value
    * Validation: A trait attribute is manifestly typed.
    * Delegation: The value of a trait attribute can be contained in another
      object
    * Notification: Setting the value of a trait attribute can fired
      callbacks
    * Visualization: With the TraitsUI package, GUIs can be generated
      automatically from traited objects.
