The problem is that client code must *define* this attribute when
subclassing BaseClass - and that's (well, in most case that should be)
the only place where they have to deal with it (unless they want to do
mumbo-jumbo thangs, in which case that's not my problem anymore !-).
What I want is to prevent client code to accidentally mess with it, and
have strange bugs that they may have hard time to fix. At the same time,
I want to have the cleanest syntax for the subclass declaration. In
fact, in most cases, the client code should not have much more to do
than defining a handfull of class attributes to end up with a
taylor-made fully functional subclass.
