There is a technical reason, which I believe Guido once gave in a post
to the now-closed py3k list as part of the thread on the change to a
single name. I do not remember, but I presume it has something to do
with a difference between executing the main module and imported
modules. Rest assured that it is intentional and has a reason. You can,
of course, check if __name__ == '__main__': to know how to access.
