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

    def decorator(func):
        if (not hasattr(func, 'wsgi_serializers')):
            func.wsgi_serializers = {}
        func.wsgi_serializers.update(serializers)
        return func
    return decorator

What's a good function header?
