[EventDispatcher] Adding IteratorAggregate to GenericEvent
---------------------------------------------------------------------------

What is the use case for this that it should be part of the Generic event?

This allows for the GenericEvent to be even more generic. Now listeners don't need to know an exact key from the arguments, but rather can iterate over the arguments to find what they are looking for. This makes the GenericEvent more like an array.

How would this be a nasty break? It's just giving the GenericEvent more capabilities with IteratorAggregate.
This is a completely separate PR from the one that flipped the constructor args.

Why are you not just doing ``foreach ($event->getArguments() as $arg) { /** ... */ }``?
If you just have ``foreach ($event)``, to me at least it would not be so clear what we are actually iterating over.

This class already has ArrayAccess. If you're already using this class like an array, then I think you should expect to be able to iterate it like an array. I'm just finishing that concept off by implementing IteratorAggregate.

Indeed, if we already have ArrayAccess which we probably don't want to remove again, then that seems reasonable.
