While we are on topic :) and as I finally understood what generational GC is[1], are there any fundamental issues with D to not use one?
I implemented one a long time ago. The only way to get write barriers with D is memory protection. It worked, but unfortunately the write barriers caused a severe performance penalty. It's possible that it might be viable with more tweaking, or in certain applications where most of the heap is not written to; I did not experiment a lot with it.
