if __name__ == "__main__" idiom broken in script launch mode

[mortenlj]

When launching a script, the script is no longer considered the __main__ module, and the common idiom for launching doesn't work.

This really should work:

def do_something():
    print("Hello world!")

if __name__ == "__main__":
   do_something()
