Once an initializer has finished running it can never be re-executed. However, an exception put in place to support multiple inheritance made reentrancy possible, breaking the expectation that there is a single execution."

Una vez que un inicializador ha terminado de ejecutarse no puede volver a ejecutarse. Sin embargo, una excepci\u00f3n puesta en marcha para soportar la herencia m\u00faltiple hizo posible la reentrada, rompiendo la expectativa de que se presenta una \u00fanica ejecuci\u00f3n"
