Given how much of EventDispatcher.cpp comes from Node.cpp, it seems like it should probably use Node.cpp's license header.

Comment on attachment 87053 [details] Patch I really like this idea. Is this this moving code? Or do I need to carefullly review each line?

Comment on attachment 87053 [details] Patch This is a depressing amount of header imports, btw. Suggesting that this class is still knows more than it should.

I've been experimenting with something like EventDispatcher<Event>, where Events has lifecycle hooks that are called at specific times, but it looks fuglier.

Some events come in troves, with multiple events dispatched as a result of one "dispatchFoo". Because they are now scoped to the same EventDispatcher, the ancestor chain calculation happens only once (yay!). So we need this extra check for size.

Even better, I'll turn it into a function explaining what's going on.
