| 97 =item operator C<new>(@args) | |
| 98 | |
| 180 | 99 Создает экземпляр объекта и вызывает конструктор с параметрами @args. |
| 49 | 100 |
| 101 =item operator C<surrogate>() | |
| 102 | |
| 180 | 103 Создает неинициализированный экземпляр объекта. |

| 49 | 108 |
| 180 | 109 Нужно заметить, что директива C<use parent> работает не совсем прозрачно, если в нашем примере |
| 110 класс C<Composite> наследуется от C<Baz>, а затем C<Foo>, то наследование от | |
| 111 C<Foo> не произойдет поскольку он уже имеется в C<Baz>. Вот не задача:) | |
