How about some syntactic sugar for " __name__ == '__main__' "?

I generally define a main() routine up near the top, then put
if __name__ == '__main__':
at the bottom. That gives you the best of both worlds; you get to see
the main() code up front in the file, but you also get to not worry
about what order things are defined.
It also means you can import your module and call its main() directly.
That's useful for testing, but occasionally for other purposes too. You
can't do that with the (detestable) style of putting a whole bunch of
code in the body of the "if" statement.
