I'm not opposed to alternative names, but I do like the current name. We `visit` each node before traversing.

`NodeVisitor` names make sense to me because 'dumping' isn't necessarily what the delegate class does. It is more consistent with what 'Visitor' usually means.

Perhaps a type name of `NodeDelegateType` and an accessor `NodeDelegateType &getNodeDelegate()` would also make sense. Then we would have eg:

```
  void Visit(const Attr *A) {
    getNodeDelegate().AddChild([=] {
      getNodeDelegate().Visit(A);
      ConstAttrVisitor<Derived>::Visit(A);
    });
  }
```
