- Visitors
- ========
- 
- To nodes.py, add ``Node.walkabout()``, ``Visitor.leave_*()``, and
- ``GenericVisitor.default_leave()`` methods to catch elements on the
- way out? Here's ``Node.walkabout()``::
- 
-     def walkabout(self, visitor, ancestry=()):
-         """
-         Traverse a tree of `Node` objects. Call `visitor`'s
-         ``visit_...`` method (upon initial entry) **and** its
-         ``leave_...`` method (before exiting).
- 
-         Parameters:
- 
-         - `visitor`: A `Visitor` object, containing a ``visit_...``
-           and ``leave_...`` method for each `Node` subclass
-           encountered.
-         - `ancestry`: A list of (parent, index) pairs. `self`'s parent
-           is the last entry.
-         """
-         method = getattr(visitor, 'visit_' + self.__class__.__name__)
-         method(self, ancestry)
-         children = self.getchildren()
-         for i in range(len(children)):
-             children[i].walkabout(visitor, ancestry + ((self, i),))
-         method = getattr(visitor, 'leave_' + self.__class__.__name__)
-         method(self, ancestry)
-
