So basically:
def run_as_thread(f):
 @functools.wraps(f):
 def wrapped(*args, **kwds):
 t = threading.Thread(target=f, args=args, kwds=kwds)
 t.start()
 return t
 return wrapped
Something like that would make defining worker threads *really* easy.
A similar idea may make sense as an addition to the
concurrent.futures.Executor ABC. For example:
def autosubmit(self):
 def decorator(f):
 @functools.wraps(f):
 def wrapped(*args, **kwds):
 return self.submit(f, *args, **kwds)
 return wrapped
 return decorator
Cheers,
Nick.
