/**
* A common base class for representing WebIDL callback function types in C++.
*
* This class implements common functionality like lifetime
* management, initialization with the callable, and setup of the call
* environment. Subclasses corresponding to particular callback
* function types should provide a Call() method that actually does
* the call.
