Ah, wasn't sure what you meant.  Well... you can do things like "return" 
in main(), that you can't do at the top level.  Sometimes I find myself 
putting a try:except: in the __main__ block, around main().  I think 
it's a habit that you develop after having written lots of scripts, and 
refactoring them, and moving stuff out of __main__ enough times that you 
just do it automatically from the start.

Also, sometimes it's actually handy to get at the command-line interface.
