Structs are ok. Classes are not. Do you really want to forbid this use case:

class A
{
     private A _parent;
     private A[] _children;

     this(A parent)
     {
         if (parent !is null) {
             _parent = parent;
	    _parent._children ~= this;
         }
     }
}

auto parent = new A;
auto child = new A(parent);
