 To avoid declaring a useless parameter just to specify the event type of the handler, there is an alternative:

 ## Compile-Time Error Checking with Event Bus AP
 
 To assist you with writing event listeners, the Event Bus AP (Annotation Processor) module enforces correct usage of the `@Event` annotation during compile time.
