ok, i understand...

but what was the reason to invent new-style classes? for now i only
learned that they can be slower a little, and you can't use them as
exceptions ( btw. is this going to change in the future )?

were the new-style classes designed to completely replace the
classic-classes at some time? or they're supposed to solve different
problems?
