      public interface TraverseprocDerived

  This is used like `Traverseproc`, but traverses only the `slots[]`-array of `fooDerived`-classes. This way we avoid that the traverse method of a traversable `PyObject` is overridden by the derived version. `gc.traverse(PyObject, Visitproc, Object)` takes care of exploiting both traverse methods.

    All Methods Instance Methods Abstract Methods
    Modifier and Type | Method and Description
    --- | ---
    `int` | `traverseDerived(Visitproc visit, Object arg)` Traverses all reachable `PyObject`s.

- - ### Method Detail

    - #### traverseDerived

          int traverseDerived(Visitproc visit,
                              Object arg)

      Traverses all reachable `PyObject`s. Like in CPython, `arg` must be passed unmodified to `visit` as its second parameter.
