technically may send "*" as an event, it isn't meant to be used that way, just
gets added to the map because of the "any event" listeners.
I see. If raising event "*" should be avoided, though, the
event_raise() function should check for that.
For someone writing new code who wants to listen for an event but does
not know exactly how the event is written, the answer is not easy to
find. I added "event list" to help with that, but based on what you
say here that's not really valid or complete, either.
