do not subclass me, I don't like to play ball this way

Just because it isn't a hash that doesn't mean you can't inherit from it. It's just implemented in a way that makes using the more traditional way of implementing objects not work. "OOP" has little to do with hashes IMO.

Subclassing of Furl is still easy. You can easily write a subclass My::Furl that overrides methods on it. What is hard is attaching additional information to the object. You've been shown various ways on how to associate information with the objects.
