Read “n月刊ラムダノート Vol.1, No.3(2019)” which was about pattern matching.

The series focus on various topics about computers. The third was “pattern matching”. (My experience for the pattern match is based on Erlang/Elixir.)

The 1st section was how it works in general, and the 2nd one was Ruby 2.7 since Ruby 2.7 will get the feature. The 2nd one was how pattern match had been implemented in Ruby rather than how we can use it effectively in Ruby. So, we could see why Ruby chosen the way.

The book is only in Japanese, but the topic was deep and it should be enjoyable to understand technical aspect in mathematical stuff in programming.
