This is really easy:
MyObject&
MyObject::self() {
    static MyObject object;
    return object;
}

This ensures the object has been initialized properly, even if it is
used in another global static objects initialization. Since 'new' is
not called, deallocation is also handled properly. The only thing that
is not guaranteed is the order in which the destructors  are called.
