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

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

What's a good function header?
