Traverses all directly contained PyObjects. Like in CPython, arg must be passed unmodified to visit as its second parameter.

Optional operation. Should only be implemented if it is more efficient than calling Traverseproc.traverse(Visitproc, Object) with a visitproc that just watches out for ob. Must return false if ob is null.
