Related to this, consider changing the signature of EventHandler
so that we can avoid the common case where instances of actions are unintentionally visited more than once. If an event handler yields and instance when ever an event occurs, and the event happens more than once, then that instance of action is visited twice. Instead we could enforce that EventHandler
returns a function that returns a new instance of the action instead of the same instance more than once. Not sure if this is possible or not, but it would be nice to avoid this logical error more easily by design.
