While you can do that nice chaining with object methods in PHP 5, you 
can't do it with array indices.

This is OK in PHP 5:

<?php

class Stooge {
     private $name = null;
     public function __construct($name) {
         $this->name = $name;
     }
     public function getName() {
         return $this->name;
     }
}

function get_object() {
     return new Stooge('Moe');
}

print get_object()->getName();
?>

It prints "Moe". But this is not:

<?php
function get_array() {
     return array('Moe','Larry','Curly');
}


// these all are parse errors:
print get_array()[1];
print (get_array())[1];
print {get_array()}[1];

?>
