I wrote the below code

    if (not resultclasses):
        raise TypeError('You    must    pass    at    least    one    argument    to    keep_lazy().')
    def decorator(func):
        lazy_func = lazy(func, *resultclasses)
        @wraps(func)
        def wrapper(*args, **kwargs):
            for arg in (list(args) + list(kwargs.values())):
                if isinstance(arg, Promise):
                    break
            else:
                return func(*args, **kwargs)
            return lazy_func(*args, **kwargs)
        return wrapper
    return decorator

What's a good function header?
