This seems inconsistent, and probably incorrect. If you were to subclass `Vector`, for instance, it would break when negating an instance of the subclass.","author":{"url":"https://github.com/Grazfather","@type":"Person","name":"Grazfather"},"datePublished":"2017-01-31T04:20:31.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/1/pythonic-api/issues/1"}
