All 4 lines of it? ;)

    subscribers = []
    
    def notify(event):
        for subscriber in subscribers:
            subscriber(event)

Seriously, though, this handles the notification but not the state
machine, which I think is critical to the effort. It also doesn't do any
error-handling for misbehaving subscribers, so not all subscribers are
guaranteed to run if there's an unhandled error in an earlier
subscriber. It also sends all events to all subscribers, instead of
partitioning the subscribers. And finally, I don't want "import
zope.event" in my framework.
