Summary: Using `EventHandlers` name was a bad idea, and I cannot tolerate it anymore. The worst part of it is that when you have a collection of `EventHandlers` objects you cannot use plural word to describe it because `EventHandlers` is an already plural word. And, this object is actually an event emitter, the thing on which we call events. Reviewed By: fkgozali Differential Revision: D8247723 fbshipit-source-id: b3303a4b9529bd6d32bb8ca0378287ebefaedda8
