[C++-sig] Function Overload Problems

[Scott A. Smith]

Try as I might, I still cannot get function overloading to work.
Here is an example that I hope someone can correct:

struct X {
    std::string Xstr;

    X() {}

     void myname(const std::string& N)
       { Xstr = N; }

     std::string myname(double xx) const
        { xx += 3.0; return Xstr; }

     std::string myname() const
       { return Xstr; }

};

BOOST_PYTHON_MEMBER_FUNCTION_OVERLOADS(Xname,         myname, 0, 1)

BOOST_PYTHON_MODULE(MyModule)
{
    class_<X>("X")
        .def("name", (       void(X::*) (const std::string&)      )0,
Xname())
        .def("name", (std::string(X::*)             (double) const)0,
Xname())
        .def("name", (std::string(X::*)                   () const)0,
Xname())
        ;
}

The first two work fine, the last one does not. What is wrong with this?
Is this the right way to use BOOST_PYTHON_MEMBER_FUNCTION_OVERLOADS? Is
there an alternative way of doing exposing these overladed functions?

Thanks,
Scott
