>hiI'm sorry I don't see anything related to namespaces in the sample. It looks like just a trick that allows to bypass restrictions imposed on class_alias(). If you need to provide a clear way on creating your very own XMLReader class in the global namespace, while the class with the same name is already registered by an extension, why not to create remove_class()/unregister_class() and/or replace_class() functions which will legitimate class removal/overriding? Still not sure if it's needed at all. With namespaces, you can create your own little world inside your private namespace and have as many overrided classes as you want.
