C++ support Interfaces in a form of abstract base classes. They aren't pointless. They force the user of a framework to use it in a defined way. You prescribe in the base class the usage of a classsystem and allow only in derived classes to variate the behavior. To appreciate Interfaces look at the Template Methode Pattern (http:// en.wikipedia.org/wiki/Template_method_pattern ) or especially at the Non Virtual Interface ( http://www.gotw.ca/publications/mill18.htm ) Idiom from Herb Sutter.
To be short C++ support Interfaces and multiple inheritace. Greetings Rainer -- http://mail.python.org/mailman/listinfo/python-list
