* an array and when a value is potentionally overriden it is added to the array. The single
         * arg option value is retrieved and instead of returning values[values.length-1] it returns
         * values[0] which means that the original value instead of the overridden one is returned
         * (first wins). With properties values are truely overriden since at the end a map is used
         * to merge which means last wins.
