Signals: Think Outside the Event.

Signals are light-weight, strongly-typed AS3 messaging tools.
Wire your application with better APIs and less boilerplate than AS3 Events.

Concept

  • A Signal is essentially a mini-dispatcher specific to one event, with its own array of listeners.
  • A Signal gives an event a concrete membership in a class.
  • Listeners subscribe to real objects, not to string-based channels.
  • Event string constants are no longer needed.
  • Signals are inspired by C# events and signals/slots in Qt.

Syntax

// with EventDispatcher
button.addEventListener(MouseEvent.CLICK, onClick);

// Signal equivalent; past tense is recommended
button.clicked.add(onClicked);

I am still looking for impressions, critiques and suggestions.
