There is this comment just above the code:
```
  // Type is __tree_iterator::__node_pointer
  // (We could alternatively also get this from the template argument)
  auto node_pointer_type =
      tree_iter_sp->GetCompilerType().GetDirectNestedTypeWithName(
          "__node_pointer");
```
Will try to see if that could work
