Thanks. Frequently though, my class instances are not attached to the DOM ...more often they're purely data classes that receive occasional updates and listen for events from one another. And it's unweildy or impossible to have them all inherit EventTarget as a base class. In any case it's overkill: I just need a fairly simple event loop to track instances, listeners and callbacks (on or off the DOM) and work as a switchboard for events, with the caveat that it's also nice to be able to pipe native events through the same switchboard when applicable.
