Description:
------------
The function get_class_function() should always return the class name of the context in which it is called. Dynamic or Static context should make no difference.

When wrapped in a parent:: call it returns the child's class name not the parent's one.

Test script:
---------------
class A {
	public static function Name() {
		return get_called_class();
	} 
}
class B extends A {
	public static function NameOfParent() {
		return parent::Name();
	}
}

echo B::Name();
echo B::NameOfParent();

Expected result:
----------------
should report "B" as Name() and "A" as NameOfParent().

Actual result:
--------------
return "B" twice, because parent doesn't change the context from B:: to A:: as it should.
