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

So here's another thought:  Have a small python script that loads and runs the actual script -- here's a POC:

--- 8< py_main ------------------------------
    #!/usr/bin/env python

    import sys
    sys.argv.pop(0)

    try:
        execfile
    except NameError:
        def execfile(file_name, globals):
            with open(file_name) as fh:
                script = fh.read()
            exec(fh, globals)

    module = {}
    execfile(sys.argv[0], module)
    module['main']()
---------------------------------------------

Put the above somewhere in your path (e.g. /usr/local/bin), make it executable, and then instead of shebanging your
scripts with `/usr/local/bin/python` you can use `/usr/local/bin/py_main`, which will load and execute the script,
calling script.main as its last act.
