But this type of thinking is the reason why the current GC is
in the state it is.
There are limitation you have in a system language, that you
don't in a VM language. That being said, D has a type system that
allow for various optimization when it come to the GC, so I don't
think it is hopeless, but we need to plug the remaining holes.
