[C++-sig] wrapping reference members

Thanks for your fast answer! I tried it with following code:

class_<Foo>("Foo", init<>())
    .def_readwrite("a", &Foo::a)
    ;

But it raises the error:

error: cannot create pointer to reference member 'Foo::a'

And it seems it's really not possible to create a pointer to a reference in c++ ;) So what else do I have to write instead of "&Foo::a"?

Cheers,
