As far as I see, all non-keyed collection type can be modelled, if we  
have just one collection type, adhering to the following criterias:

1. Must be an ordered (not sorted) collection.
2. Elements must not be restricted to a certain type.
3. Offering the following functions (ObjC notation):
	1. -count
	2. -objectAtIndex:
	3. -removeObjectAtIndex:
	4. -insertObject:atIndex:
