PHP list weirdness

list.php

<?php
$one = array('two', 'one');
list($two, $one) = $one;
var_dump($one, $two);
/* Output
string(3) "one"
string(1) "o"
*/

/*
Reason: http://us1.php.net/list#refsect1-function.list-notes

list() assigns the values starting with the right-most parameter.
If you are using plain variables, you don't have to worry about this.

Modification of the array during list() execution (e.g. using
list($a, $b) = $b) results in undefined behavior.
