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.
