这是什么
Does the text describe asking questions for every possible branch up front and consuming only the ones matching the chosen branch?
这些不算
Asking follow-up questions only after the first answer arrives.
这道题在 Jev 眼里长这样
jevbooks 就是拿这道题去问 Jev 每一份 README 的。抄结构，别抄字面。题目原文是英文——这就是发给 Jev 的字面内容；state 可以是中文。
