- EventHandler::RemoveHandlerEvent
- EventHandler::Event
- Reference

Overview
Meta event, emitted whenever a handler is removed from any event, including itself.
When AddHandlerEvent and RemoveHandlerEvent are emitted, they invoke
their handlers with the Wrapper object. A wrapper object for each
handler is implicitly created on every on(), and in addition to providing
access to the handlers themselves, wrappers also contain the values of
arguments used during handler subscription (values of once?, async?,
and at). This allows listeners on these meta events full insight into
the added handlers and their settings.
