PDD15 says that both classes and objects have a list of attributes and it is possible to add or remove attributes to a class but not an object.
Am I right in thinking that the attribute list for an object is just a copy of the attribute list for the class, which is used to store the objects values?
It seems that for Ruby instance variables can be modelled using attributes, but I couldn't see any way of handling class variables. So, what is the recommended way of handling them?
