References as key in Ds\Map() not work

[botanegg]

Hi!
I newbie in php, and i have a problem with Ds\Map()
If I use a reference as a key or I use variable with a reference as a key Ds\Map cannot found my value.

Reproduce code:

<?php
$map = new Ds\Map();
$str = "test_key";
$str_ref = &$str; // comment uncomment this
$map[$str] = "stored"; // try $str_ref too
if ($map->hasKey($str)) { // try $str_ref too
    echo "found";
} else {
    echo "not found";
}

This was only an issue when using array access syntax. Fixed in cc6527e and released as v1.1.10
