for the "right time" you can choose to spin a thread and wait to the end of
the load of the module
something like
from threading import Thread, current_thread
def run_func(func, module_thread):
module_thread.join()
func()
def main(func):
if func.__module__ == '__main__':
Thread(target=run_func, args=[func, current_thread()]).start()
return func
