### 示例

示例 #1 Ds\Map::merge() example

    <?php
    $map = new \Ds\Map(["a" => 1, "b" => 2, "c" => 3]);

    print_r($map->merge(["a" => 10, "e" => 50]));
    ?>

以上示例的输出类似于：

    Ds\Map Object
    (
        [0] => Ds\Pair Object
            (
                [key] => a
                [value] => 10
            )

        [1] => Ds\Pair Object
            (
                [key] => b
                [value] => 2
            )

        [2] => Ds\Pair Object
            (
                [key] => c
                [value] => 3
            )

        [3] => Ds\Pair Object
            (
                [key] => e
                [value] => 50
            )

    )
