Making a field static is effectively a global variable to the

I have a recursive class structure(think of a graph or tree)
and I need to keep a global state for it, but this state
actually needs to be different for each tree object. The
reason for this is that structurally it will not change per
tree and if it it is not static then it wastes space
unnecessarily.

Is there any way to do this more naturally in D?
It seems to me like the obvious solution is to use two
different classes, one to store the global state, and one to
store the individual objects in your structure. For example:
class Tree {
State state;
Node root;
}
class Node {
Node[] children;
}
So I have a Node. How do I find the Tree it belongs to?
