It's also distracting for more advanced readers who are trained to spot this pattern in code reviews.\n\nIMO this example would be clearer if `grade` accepted no arguments besides `score` and the defaults were inlined.\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-145270\n* gh-145367\n* gh-145368\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/ngoldbaum","@type":"Person","name":"ngoldbaum"},"datePublished":"2026-02-26T19:45:56.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/145269/cpython/issues/145269"}
