That really depends, but a tracing GC is easier to use, as it 
catches cycles. So it would be better to have an incremental 
collector.

But I don't think D can get there within 5 years, and do people 
want to discuss what D could have in 5 years?  I think we need to 
figure out what the time frame should be.

You could get non-optimized ARC in 6 months.
And basic optimized ARC in 12 months.
Optimized ARC in 18 months.
Opiimized ARC with borrow checker in 24 months.

That is a lot more attractive IMO.

Open Source should focus on strategies which can be done as small 
incremental steps and ARC can be made compatible with 
std::shared_ptr when it is allocated with std::make_shared. That 
is a big plus.
