so name your events property "@RickWaldron at events".

If somebody subclasses Emitter and know that property name, then they must be doing something intentional.

Unique Symbols don't guarantee that sort of integrity. All you've accomplish by using them as in your example is to minimize that chance that somebody else doesn't accidentally use the same property name for some other purpose.  Naming your property "@RickWaldron at events" also makes such accidentally unlikely.
