Well, normally, when I'm a newbie, and this happens everytime I try a new 
language community, I not only try to learn the rules, but also the useful 
idioms. Basically while it's usually quite easy to learn a language, it's 
more complicated to get a feeling for the language.

I've also got the impression that you ignore the fact that Python is quite a 
mature language (I personally have been maintaining a commercial solution 
written in Python since 1996 ;) ), and that is not a wise thing to do.

And lastly your proposition is quite popular only with newbies that don't 
know Python. Actually it is already implementable with Python now:

UnknownName="UnknownName"

class ProtectedValues:
  def __init__(self):
    self.a=1
    self.b=2
    self.classsetup=1

  def __setattr__(self,k,v):
    if self.__dict__.has_key("classsetup"):
      if not self.__dict__.has_key(k):
        raise UnknownName
    self.__dict__ [k]=v

x=ProtectedValues()
x.c=100 # -> UnknownName

# Warning: I've typed this in my Mailer, and didn't test it. So the
# indentation is propably wrong ;)

But then, You said You were a newbie. ;) You just didn't behave like a 
newbie, by proposing obviously a very non-Pythonish change. But then, perhaps 
I should tell the guys at Audi, that my A6 should have 6 tires instead of the 
4. As a newbie in car design I know it better than them.
