		# Second, groups actually do not exist as collections. Iterating in
		# groups works by checking all properties on each iteration and
		# testing which one is the m-th property of the group!
		# So these inefficient _memberCount() and _groupMember() are provided
		# for the sake of completeness, but don't use them without a good reason ;-)
