RFC: Const array/string dereference

Introduction

A little improvement to make things consistent.

Proposal

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

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

?>

I wrote a patch to make php support const array/string dereferencing. After the patch, the following script works:

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

Vote

do you think it is okey to apply this to TRUNK(not 5.4)?
