you should not be using Prototypes in AS3, from what i understood the way it
gets used is you can add properties on methods
private function mymethod():void{
//you can do something like thi
mymethod.yahooGroup="Flex Coders";
}

Subject: [flexcoders] Re: Example of Object.isPrototypeOf ()
What exactly does it mean when the Flex doco says:
"This method returns true if the object is in the prototype chain of
the object specified by the the Class parameter." What
does "prototype chain" mean here? Sorry for my ignorance if this is
a dumb question. And are you saying this is an obsolete method?
