foo.h is:

____________________

class foo {
public:
  virtual foo* bar();
};

_____________________

foo.pyste is:

______________________

foo = AllFromHeader('./foo.h')
set_policy(foo.foo.bar,return_internal_reference())
________________________

then (current cvs) pyste gives you:

// Includes ====================================================================
#include <boost/python.hpp>
#include <./foo.h>

// Using =======================================================================
using namespace boost::python;

// Declarations ================================================================


namespace  {


struct foo_Wrapper: foo
{
    foo_Wrapper(PyObject* self_, const foo & p0):
        foo(p0), self(self_) {}

    foo_Wrapper(PyObject* self_):
        foo(), self(self_) {}

    foo * bar() {
        return call_method< foo * >(self, "bar");
    }

    foo * default_bar() {
        return foo::bar();
    }

    PyObject* self;
};



}// namespace 


// Module ======================================================================
BOOST_PYTHON_MODULE(foo)

    class_< foo, foo_Wrapper >("foo", init<  >())
        .def(init< const foo & >())
        .def("bar", &foo::bar, &foo_Wrapper::default_bar)
    ;

}
