 To write tree visitors for the parse trees that are RPython, there is a special
-metaclass ``CreateDispatchDictionaryMetaclass`` in ``pypy.rlib.parsing.tree``_
-to use. If your class uses this, it will grow a ``dispatch(node)`` method, that
-calls an appropriate ``visit_<symbol>`` method, depending on the ``node``
-argument. Here the <symbol> is replaced by the ``symbol`` attribute of the
-visited node.

 For the visitor to be RPython, the return values of all the visit methods need
 to be of the same type.
