Remarks
The shape of a global object can dynamically change either through simple state changes or through modifications to it members.

The default implementation of PerformChange performs the following sequence of actions:
Raises the Changing event.
Sets the object instance to a null value by calling the ClearInstance and ClearObjectType methods.
Raises the Changed event.
