Unless it has changed since I last used it (~ v1.5), Python does not have
nested scopes, so it's relatively flat. Even C has nested scopes, just not 
nested function definitions. 

Ada allows you to define classes at arbitrarily deep levels of
scope. Python doesn't even allow you to create deeper levels of scope. 

OK, I just hit the Python page and

http://python.sourceforge.net/peps/pep-0227.html
http://www.amk.ca/python/2.1/index.html#SECTION000300000000000000000

confirm that 2.1 will no longer be a "flat" language.
