• @allObjects passing null for the function produces

    Uncaught TypeError: Second argument to EventEmitter.on(..) must be a function or a String (containing code)

    And I do not want to provide a dummy function, since removing an event handler may (now or later) be used for internal optimization (as no handler has to be called if none has been provided)

    @Gordon great, thank you! Is there also a possibility to uninstall a specific handler only?
