Quine - a program that prints its own source code (implementation example in Ruby)

In the article 'Quine in Quine', author Julius discusses the fascinating phenomenon in programming known as quines. A quine is a program that can output its own source code as a result of execution. These types of programs are interesting as they help to understand self-reference in programming and logic. Julius presents different methods of implementing quines in various programming languages, with a particular focus on Haskell. Code examples illustrate how to create a quine, showcasing the unique syntactical features of the language used. The author concludes the article with a reflection on the significance of quines in computer science and their potential applications in various areas of programming.
