Currently, the Parameter objects in the signature have the information about the parameter names and defaults, but their annotation is not set.\r\n\r\nThus, I would like to propose setting the annotation of the Parameters in the Signature object as well.\r\n\r\n(Initially posted as http://bugs.python.org/issue31006.)","author":{"url":"https://github.com/anntzer","@type":"Person","name":"anntzer"},"datePublished":"2017-07-28T19:54:29.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/454/typing/issues/454"}
