Description:
------------
I?m trying to use Reflection API. I works great, but I?ve some remarks regarding ReflectionException. Calling ReflectionParameter::getClass() will raise an exception when class definition isn?t already included. That?s fine, it?s an expected behavior. The problem is that I have no way to get the missing class name. Ok, I could parse message string, but this way it becomes (unintentionally) part of  the public API. What do You think about having sth like

Class ReflectionExceptionClassNotDefined extends ReflectionException
{
	public string getClassName();

}


Reproduce code:
---------------
class A
{
    public function __construct(B $b)
    {
       $this->b = $b;
    }
}

$rc = new ReflectionClass('A');
$rconstr = $rc->getConstructor();
$rparams = $rconstr->getParameters();

try
{
   $paramclass = $rparams[0]->getClass();
}
catch (ReflectionException $e)
{
   //no way to get 'B' name here, without parsing msg string
}
