Lines 32 to 38 in 5f47b07

	def clone(self, **attrs: Any) -> None:
	"""Clone a prototype and update inner attributes dictionary"""
	# Python in Practice, Mark Summerfield
	# copy.deepcopy can be used instead of next line.
	obj = self.__class__(**self.__dict__)
	obj.__dict__.update(attrs)
	return obj

According to type hint None type should be returned but obj of type Prototype is returned.
