But I try to word it differently.

I have a game with GameObjects, a system manages those GameObjects.
GameObjects can hold a pointer/reference to each other.

But at one point a GameObject dies and when it does it shouldn't be able
to be accessed by other GameObjects nor should it be kept alive in memory.

How do I express this in D?

I have also looked at core.memory.GC

   auto foo = new Foo!int();
   auto foo2 = foo;
   GC.free(foo);

   if(foo != null)
     writeln(*foo);
   if(foo2 != null)
     writeln(*foo2);

But it seems that `GC.free` behaves like C++'s `delete` and doesn't
actually null all the pointers.

Correct, in native land you can't null all the pointers.
They are just integers after all.
