Or are we supposed to fix our annotations in some way?\r\n\r\nThanks in advance!","author":{"url":"https://github.com/levincarmel","@type":"Person","name":"levincarmel"},"datePublished":"2022-11-10T08:31:45.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/9145/typeshed/issues/9145"}
