Малоизвестный синтаксис плюсов.
1. Инициализация целочисленного значения из строки (используется в строках-классах времени компиляции).
2. Константная ссылка на стековый объект (используется для создания DSL, в т.ч. boost::spirit).
P.S.: Более полный вариант со строками лежит на форуме.

Была задача за минимальное кол-во строк реализовать простой тетрис. Особого внимания заслуживает 6 строчка кода. Всё очень плохо?
