A typical usage is to piggyback data on objects in a list.
Say you have a list of specific objects, eg. Car objects.
Now you want to add a property driver without changing the Car class.
By using a dictionary you can reference the driver by means of the car
instance.
var porsche : Car = new Car("Porsche");
var bmw : Car = new Car("BMW");
var bokel : Driver = new Driver("bokel");
var maciej : Driver = new Driver("maciej");
var drivers : Dictionary = new Dictionary();
drivers[ porsche ] = bokel;
drivers[ bmw ] = maciej;
var winningCar : Car = getWinningCar();
var winningDriver : Driver = drivers[ winningCar ];
