   [PEP-484](https://www.python.org/dev/peps/pep-0484/#id29) says:
   
   > A past version of this PEP allowed type checkers to assume an optional type when the default value is None.
   ...
   This is no longer the recommended behavior. Type checkers should move towards requiring the optional type to be made explicit.
