	<brief_description>
		Internal class used by [PackedDataContainer].
	</brief_description>
	<description>
		When packing nested containers using [PackedDataContainer], they are recursively packed into [PackedDataContainerRef] (only applies to [Array] and [Dictionary]). Their data can be retrieved the same way as from [PackedDataContainer].
		[codeblock]
		var packed = PackedDataContainer.new()
		packed.pack([1, 2, 3, ["abc", "def"], 4, 5, 6])

		for element in packed:
		    if element is PackedDataContainerRef:
		        for subelement in element:
		            print("::", subelement)
		    else:
		        print(element)

		# Prints:
		# 1
		# 2
		# 3
		# ::abc
		# ::def
		# 4
		# 5
		# 6
