Generational GC is a reusable concept. It’s very important for those who go to apply this concept to understand what you need to build a generational GC. My point is that you don’t need copying to do generational GC. The only thing that generational GC has to do with copying is that this is how the first generational GCs happened to be implemented and some people don’t know that there is another way, probably because people like you refuse to acknowledge that copying has nothing to do with generations.

You seem to be treating “generational GC” as a historical concept rather than an algorithmic concept. You’re right that from an historic perspective, generational GC and copying are related. But they are not technically or theoretically related.

Um, I'm well aware that generational GC doesn't require copying, and I mentioned this from the start. I don't even know what we're arguing about anymore.
