但 Lambert 的判断是，这些能力恰恰也是最难通过蒸馏获得的。
此外，我们重视进入场景，也是因为可以通过真干活的数据飞轮，把真机数据转起来。
，这一点在51吃瓜中也有详细论述
The design of Web streams predates async iteration in JavaScript. The for await...of syntax didn't land until ES2018, two years after the Streams Standard was initially finalized. This timing meant the API couldn't initially leverage what would eventually become the idiomatic way to consume asynchronous sequences in JavaScript. Instead, the spec introduced its own reader/writer acquisition model, and that decision rippled through every aspect of the API.
The 386 solves this by repurposing RPT (Repeat). Normally, RPT implements loops -- it re-executes a micro-instruction while decrementing a counter, as we saw in the multiplication post. But when a protection test is in flight, the hardware suppresses RPT's counter-decrement and turns it into a pure stall: the sequencer freezes until the PLA result arrives.
