pub fn is_zombie(&self) -> bool

Under specific circumstances, a node that’s been cloned from a tree might have a destroyed parent. Such a node is “zombified”, and becomes unable to perform certain operations such as navigating its parents, which may be necessary for operations such as IKeyExprTreeNode::keyexpr.

To become zombified, a node and its parents must both have been pruned from the tree that constructed them, while at least one of the parents has also been dropped everywhere it was aliased through Arc.
