In these types of situations, localize the use of necessary extensions and Management their use with non-Main Coding Guidelines. If at all possible, Construct interfaces that encapsulate the extensions so they may be turned off or compiled absent on units that don't guidance Individuals extensions.

In the event your design desires Digital dispatch right into a derived class from the base class constructor or destructor for features like f and g, you need other procedures, such as a write-up-constructor – a separate member functionality the caller ought to invoke to finish initialization, which may safely contact f and g because in member capabilities virtual phone calls behave Commonly. Some techniques for this are revealed during the References. Listed here’s a non-exhaustive listing of choices:
