In addition to the other answers, it's worth noting that most
every good modern GC algorithm I can think of requires
barriers. Walter has repeatedly and emphatically declared that
D will not have barriers, so we're kind of SoL on on that
front. Java and Go don't have that problem.
Barriers are only necessary if you want a low-latency or
concurrent GC, afaik. I'm not sure if low-latency is worthwhile
for D. If latency is important, you might be better off to
disable the GC (partially). Concurrent is nice for servers, where
you do not care about memory consumption.
D does not even have a precise GC so far and that fruit hangs
much lower. It is a precondition on basically any advanced GC
techniques.
