the biggest gain from & and ~ is that they let you mix and match regexes. instead of writing a single spaghetti monster regex that tries to do everything, you can break it down into smaller, simpler pieces and then combine them with boolean operators. this makes your regexes easier to read, write and maintain. this is best illustrated in the web app that came with the paper (https://ieviev.github.io/resharp-webapp/) where you can visually see how the different components of a regex are combined, and how they contribute to the final match.

结合美以2025年空袭伊朗与之后伊朗军工恢复情况看，美以情报部门估计伊朗至多储备约500枚能打到以色列的中程弹道导弹，而覆盖中东美国基地的近程导弹数量在1100枚左右，特别是2025年打击行动中，经视频确认被摧毁的伊朗导弹发射车达到128部，占总数的1/3，如果每辆发射车在被摧毁时都载有导弹，则伊朗的导弹库存可能进一步降低。随着伊朗西部导弹发射阵地被摧毁或压制，革命卫队不得不从更靠东的纵深发射数量有限的远射程导弹，从而进一步限制可发射量。
Instead, you should treat Business-Modules as the units you want to test. A module has a clear, explicit API (public methods as well as required interfaces). It means that all the results and side effects can be observed via the API. So in tests you can apply stimulus to the module and assert the results/side effects - that should cover all possible paths (except for time based logic, but there are other methods to cover these cases).
