PHP version:      5.6.11
Package:          PHP Language Specification
Bug Type:         Feature/Change Request
Bug description:Allow default values for list()

Description:
------------
Sometimes I want to use the list() construct to unpack an array, but I
don't know the size of the array. In this case, list() will give me a
"Notice: Undefined index ..".

It would be nice if I could specify default values, as in the code
below.

Test script:
---------------
<?php

list($a, $b = 'bbb', $c = 'ccc') = array('AAA', 'BBB');
print "$a, $b, $c";

// Output: "AAA, BBB, ccc".
