yield_self is more awesome than you could think

…the name still sucks, tho As you probably have been told, Ruby 2.5 has introduced Kernel#yield_self method, now available in any object. On the first sight, it does nothing fancy: just, as the name suggests, yields object it is applied to and returns the result: # before url = construct_url response = Faraday.get(url) data = JSON.parse(response.body) id = data.dig('object', 'id') || '<undefined>'

yield_selfこんな使い方もあるのかー。って感心するけど実際のプロジェクトでこの使いかたするかと言われるとうーん

yield_selfがEnumerator返すからOption型とかResult型みたいな書き方ができるっぽい
