sorry about inappropriate vocabulary. I imagined that, somewhere in the
instance, there is variable referencing what class it belongs to. In Python
it's a tuple hat can be replaced. I was asking if there is something similar
in Ruby. So I suppose the answer is no, and I'd better open up GoF again...

I'll look in to that pattern.
