I have a perl variable like this. **How can i access the inlying properties (like '706')?**

```
my @config = [
        {
        'x' => [ 565, 706 ],
        'y' => [ 122 ],
        'z' => 34,
        'za' => 59,
    }
];

```

**EDIT:** `print Dumper($config[0]);` yields : `$VAR1 = undef;`

Looks like i get acces using `$config[0][0]->{x}[1];`. Why do i have to use [0][0] (one is clear, but he ssecond...)?

**EDIT2:** I am sorry for changing the data structure, but the definition which was given to me changed.
