You might assume this pattern is inherent to streaming. It isn't. The reader acquisition, the lock management, and the { value, done } protocol are all just design choices, not requirements. They are artifacts of how and when the Web streams spec was written. Async iteration exists precisely to handle sequences that arrive over time, but async iteration did not yet exist when the streams specification was written. The complexity here is pure API overhead, not fundamental necessity.
舉例來說，汽車產業一直是中德關係的核心支柱，貢獻德國對中國出口的近三分之一。但近年中國汽車業崛起，根據榮鼎集團數據，2025年德國汽車對華出口暴跌66%至2009年最低，中國電動車品牌如比亞迪、蔚來在歐洲市場份額則從2020年的不足1%躍升至2025年的12%。
