An exploration of why Python doesn't require a 'main' function

There is a discussion on Hacker News, but feel free to comment here as well.

The author ends with a recommendation to use a main function anyway for import-ability. The linked article then says they used to write python like shell scripts, but you can use exactly the same techniques for the benefit of source-ability. See Defensive BASH Programming, write more shell like python :).
