Description:
------------
Maybe it's not a bug, but I cannot call private or protected methods from within a class by ReflectionClass.

Test script:
---------------
<?php

class Test
{
	static public function instance()
	{
		$class=new ReflectionClass(get_called_class());
		return $class->newInstanceArgs(func_get_args());
	}
	
	private function __construct()
	{}
}

Test::instance();

Expected result:
----------------
Create a new instance.

Actual result:
--------------
Fatal error: Uncaught exception 'ReflectionException' with message 'Access to non-public constructor of class Test'
