<div class="block">Used in event handler registration in place of its associated event handler.
 Its sole purpose is to break the otherwise strong reference between an event
 handler container and its associated event handler. While the container still
 holds strong reference to the registered <code>WeakEventHandler</code> proxy, the
 proxy itself references the original handler only weakly and so doesn't
 prevent it from being garbage collected. Until this weak reference is broken,
 any event notification received by the proxy is forwarded to the original
 handler.</div>
