allow definition of custom events in (class) interfaces
If a class is used as an interface by using it with the Implements keyword it unfortunately isn't possible to define custom events in this interface definition.
It would be more or less necessary to support those custom events in interfaces for mature object oriented programming.
Even before adding this as a new feature it would be more important to make it possible to use Interfaces without crashes. Using a big project with a lot of "Implements" causes a completely instable application which crashes all the time with the only solution to remove interfaces at all. I've referred to this here:
