	<brief_description>
		An internal class used by [PackedDataContainer] to pack nested arrays and dictionaries.
	</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, ["nested1", "nested2"], 4, 5, 6])

		for element in packed:
			if element is PackedDataContainerRef:
				for subelement in element:
					print("::", subelement)
			else:
				print(element)
		[/codeblock]
		Prints:
		[codeblock lang=text]
		1
		2
		3
		::nested1
		::nested2
		4
