// create a xml archive, deserialize w
widget w = create_widget("description.xml");

// case 1

window w2 = cast<window>(w);
grid g = cast<grid>(w2->at(0));
button b = cast<button>(g->at(0, 0));
b->clicked_signal = my_callback;

// case 2

button b = cast<button>( w->find_by_name("my_button") );
b->clicked_signal = my_callback;

// case 3

button b = cast<button>( w->find_by_path("my_grid/my_button") );
b->clicked_signal = my_callback;

// case 4

// do nothing, a Python function is automatically attached to clicked_signal
// Python should be able to see the widget as an object
// Nontrivial
