| From time to time objects have to be cached and exchanged between various instances. Parameters and public methods are very useful for this purpose, but we do not always want to pass an object on across countless instances to the target. Also, the required objects are not always located in the same scope. | From time to time objects have to be cached and exchanged between various instances.

| - | The standard hashtable manages exactly one value per key. However, often more than one value per key has to be stored. In this case, a list has to be used as a value, in which a number of individual values are saved. This is not particularly difficult but a tedious and boring task. | + | The standard hashtable manages exactly one value per key. However, often more than one value per key has to be stored.
