Esta función devuelve la porción de <parameter>haystack</parameter> la cual

comienza en la última aparición de <parameter>needle</parameter> y que va

hasta el final de <parameter>haystack</parameter>.

Si <parameter>needle</parameter> contiene más de un caracter,

Si <parameter>needle</parameter> no es un string, se convierte en
