ClutterEvent is not really gobject-introspection friendly because of the whole discriminated union thing. In particular, if you get a ClutterEvent in a signal handler, you probably can't access the event-type-specific fields, and you probably can't call methods like clutter_key_event_symbol() either, because you can't cast the ClutterEvent to a ClutterKeyEvent. The cleanest solution is to turn every accessor into ClutterEvent methods, accepting a ClutterEvent* and internally checking the event type.
