Here's a good function header given the following:
I wrote the below code

    def deco(f):
        def wrapper(*args, **kwargs):
            if ('name' in b_kwargs):
                _b_kwargs = b_kwargs
            else:
                _b_kwargs = dict(b_kwargs, name=f.__name__)
            f_rval = f(*args, **kwargs)
            domain = Domain((lambda x: x), f_rval, **_b_kwargs)
            return domain
        wrapper.__name__ = f.__name__
        return wrapper
    return deco

What's a good function header?
