Description:
------------
In php versions up to 5.3.0RC4 <?= 'output'; ?> would print the word output to the screen. As of 5.3 this no longer works, instead outputs chunks of code to the screen.



Reproduce code:
---------------
class action {
  private $request = array('foo' => 'bar');

  public function getRequest($key, $default) {
    return isset($request[$key]) ? $request[$key] : $default;
  }
}

... some other stuff...

$array = ('key' => array('bar' => array('value' => 'foo')));

<?= 'output'; ?>
<?= $array['key'][$action->getRequest('foo', NULL)]['value']; ?>

Expected result:
----------------
output
bar

Actual result:
--------------
action-&gt;getRequest('foo', NULL)]['value1']; ?&gt;
