    Every VBA collection provides the number of items, an enumeration access of
    all collection items (e.g. for the "For Each" loop), and a way to access
    single items, usually via the method "Item".

    The various VBA collection objects expect a specific number of arguments in
    the "Item" method, therefore this method is not part of this base interface
    but has to be specified seperately in every derived interface.
