====== RFC: Const array/string dereference ======
  * Version: 1.0
  * Date: 2011-11-30
  * Author: Xinchen Hui <laruence@php.net>
  * Status: Implemented in PHP 5.5
  * First Published at: https://wiki.php.net/rfc/constdereference

===== Introduction =====

A little improvement to make things consistent. 

===== Proposal =====
Base on feature request: https://bugs.php.net/bug.php?id=60408: 

<code>
Please add array constructor dereferencing support

like JavaScript, C# and all languages excluding PHP 5.4

<?php

 $i=0;
 print(array('pa','th')[$i++]); // pa
 print(['wa','ss'][$i++]); // ss

?>
</code>

I wrote a patch to make php support const array/string dereferencing. After the patch, the following script works:
<code php>
echo array(1, 2, 3)[0]; //output 1
echo "foobar"[2]; //output o
echo "foobar"["foo"][0] // output f

echo [1,3,4][2]; //output 4
</code>
