Think of code like this (let's assume the "break" statement is used for stopping module execution):

There's a subtle bug here that shows that the proposed feature has its awkward points: you probably want to execute the "if __name__ == '__main__'" block in the C extension case as well.
No, you don't :-) If you would have wanted that to happen, you'd put the "if __name__..." into the else: branch.
Not sure I understand. Your example code is flawed because it doesn't execute the main() for the C extension case. Of course you can duplicate the code in the else branch, but you didn't do it in the first place, which was the bug. Georg
