It would probably need to be called something else, because main is
often the name of the main function... but you could write such a
decorator now if you really wanted to.
def mainfunc(fn):
if fn.func_globals.get('__name__') == '__main__':
# ensure the function is in globals
fn.func_globals[fn.__name__] = fn
fn()
return fn
@mainfunc
def main():
print 'this is in __main__'
