public class EventDispatcher<T = Event>:
Multicast dispatcher generated behind event declarations.
Application code normally declares public event clicked as ActionEvent and uses +=, -= and emit this.clicked(...). This class remains public only so the compiler can materialize concrete generic dispatchers and advanced code can inspect the registered handler count when needed.
dispatcher = EventDispatcher<Event>() dispatcher += lambda(e: Event): print(e.source)
