Some of the design patterns rely on the implementation of abstract classes. Actionscript unfortunately do not support this. Some facts about abstract classes: Abstract classes cannot be instantiated. They have to be extended by subclasses. Ive been working with design patterns for a long time, and have had some really good experiences in the past when im refactoring code and enforcing the use of patterns. In the following tutorials i plan to give brief explanations on each pattern, how to use it and example code where the pattern is being used. Im [...] The command pattern is a design pattern in which an object is used to represent and encapsulate all the information needed to call a method at a later time. This information includes the method name, the object that owns the method and values for the method parameters.
A facade is an object that provides a simplified interface to a larger body of code, such as a class library.

I have been using them since i started programming. Now im doing most of my work in java and actionscript and in one of my opensource projects i had to avoid using the actionscript event model.
