If I right click on the class name, "Find Declaration" goes to the class definition:

$validator = new Zend_Validate_EmailAddress();

But if I right click on the class name in a type hint, there's no "Find Declaration" menu option:

public function __construct($allow = Zend_Validate_Hostname::ALLOW_DNS, $validateMx = false, Zend_Validate_Hostname $hostnameValidator = null)

So there's no fast way to get to Zend_Validate_Hostname.

Please add "Find Declaration" support for type hints. (http://us3.php.net/manual/en/language.oop5.typehinting.php)

Thanks!
