Short Coding ~職人達の技法~

Short Coding ~職人達の技法~

（いきなりですが）読破。
一見すると無茶苦茶に見えるけど（ちゃんと）整理されている理論、常識を逸脱した考え方、無駄な事は一切行わず使えるものは何でも利用する精神、そして自分自身を信じて貫き通す信念みたいなものを感じました。
深いところまで処理系の仕組みを熟知しているからこそ可能な芸なんでしょうかね。ここまでくるとアートだね。
Short Codingに興味がある訳ではないのですが、あまりの凄さに、ちょっと吐き気が。。。後、今後の役に立つかは不明。（ｗ

5.2.4 ready?

この辺を参照されたし。
時間が経てば玉（アーカイブ）もできるでしょう。。。きっと。
5.2.3から5.2.4までの修正状況は以下の通り。
今回も変更点が多いので時間を見つけて精査したい。
