| 97 Создает экземпляр объекта и вызывает конструктор с параметрами @args. | |
| 98 | |
| 99 =item operator C<surrogate>() | |
| 100 | |
| 101 Создает неинициализированный экземпляр объекта. | |

| 165 | 107 Нужно заметить, что директива C<use parent> работает не совсем прозрачно, если в нашем примере |
| 49 | 108 класс C<Composite> наследуется от C<Baz>, а затем C<Foo>, то наследование от |
| 109 C<Foo> не произойдет поскольку он уже имеется в C<Baz>. Вот не задача:) | |
