The EventStack
solves two design problems:
element.addListener()
.The EventStack
is a public API that allows subscribing a DOM node to events. The event subscription for
each unique DOM node creates a new EventTarget
object.

| EventStack | +------> | EventTarget |

+------------+ +-------------+
Each EventTarget
is assigned to an unique DOM node. An EventTarget
tracks event handlers for
the target's DOM node. Making multiple subscriptions to a click
event for a single DOM node will
result in a single registered handler
for that DOM node. An EventPool
also handles EventPool
relations, it stores only unique pools.

A handler
is a generated function that will notify the corresponding subscribed EventPool
.
An EventPool
notifies its EventSet
, while an EventSet
stores a set of subscribed
event handlers. An EventSet
is also responsible for event ordering and dispatching to
subscribed handlers.
