ok. Now I have

    python::class_<Foo,
                   boost::shared_ptr<Foo>,
                   boost::noncopyable> hello("Foo");

but the compiler complains. You use a 'assert_default_constructible'
class to make sure 'Foo' can be default-constructed, though obviously
in my case it shouldn't (only the factory should construct 'Foo's).
What am I missing ?
