Help us understand the problem. What is going on with this article?

#Ruby インスタンスのメソッドを上書きして #Rails の current_user の update を禁止する例、的な。

もしくはインスタンスの特異メソッドをoverrideして、オープンクラス的なことをやる、的な。

user = User.first
user.define_singleton_method(:update, -> (*arg) { raise 'Unable update!' })

user.update
# RuntimeError: Unable update!

これを Rails の @current_user に対してやれば、update を禁止できるのでは?

(目的については特に語らない)
