Sorry, I missed this email as it went to an unexpected folder.
You suggest that creating a class on the fly can be done. Since the
set of classes would be infinitely variable, but in each individual
case, it could be determined by interpreting data that is read in, or
a description file format I plan to use, then creating classes on the
fly (if reasonably trouble-free) would be desirable in my case.
Maybe just for starters, are there methods like "create new class",
"add instance variable of type X", etc. I would be really surprised,
but it could be useful to me. Thanks.

think that using either Ruby or Python to gain dynamic class

rather ignorant position of only casually following this thread,
I'm not sure that dynamic class generation is an appropriate
solution. It could be done, but I don't see an advantage over
creating a set of classes that effectively model whatever it is you
are trying to model. That can be quite dynamic and creating
generic, dynamic, containers can vastly simplify lots of things
(archival, for example). This is exactly what CoreData does with
NSManagedObject and entities -- you don't need to subclass
NSManagedObject to store a particular entity.
