Hi Bruno, hi folks! thank you very much for your advices. I didn't know about the property function. I learned also quite a lot now about "references". Ok everything is a reference but you can't get a reference of a reference...
I saw a lot of variations on how to solve this problem, but I find actually that the "property approach" is the most natural of all. Basically the idea there is that you build up this list of class attributes not by storing a reference to a class attribute (which seem to be impossible), but you just store on each element of the list one method (pardon a reference to..) to get the associated class attribute. Sorry for the UnPythonity. I used to be a CamelRider. But not very longtime ago I left the Camel in the Desert, because I met the Snake....
