I wrote the below code

    private_name = ('_' + name)
    @deprecated(since, name=name, obj_type='attribute')
    def get(self):
        return getattr(self, private_name)
    @deprecated(since, name=name, obj_type='attribute')
    def set(self, val):
        setattr(self, private_name, val)
    @deprecated(since, name=name, obj_type='attribute')
    def delete(self):
        delattr(self, private_name)
    return property(get, set, delete)

What's a good function header?
