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.
