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

        (
            [key] => a
            [value] => 1
        )

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

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

)
