# Summary of Keynote: Keep Ruby Weird

The keynote speech by Yukihiro Matsumoto, affectionately known as Matz, at the Keep Ruby Weird 2018 conference focuses on the unique aspects and complexities of Ruby's keyword arguments, introduced in Ruby 2 to enhance the language's functionality.

## Key Points Discussed:
- **Introduction to Ruby's Weirdness**: 
  - Matz highlights the quirky nature of Ruby and discusses how the community embraces this weirdness.

- **Keyword Arguments in Ruby 2**: 
  - Matz explores the introduction of keyword arguments in Ruby 2, explaining their implementation and how they enhance code readability and usability.
  - He compares Ruby's keyword arguments to those in other programming languages like Python, Smalltalk, and Swift, pointing out the unique attributes of each language's handling of keyword arguments.

- **Background**: 
  - The talk reflects on Ruby's evolution since its inception, particularly the changes introduced with Ruby 1.9 that paved the way for keyword arguments. These changes included expanded hash arguments and simple hash syntax.

- **Syntax Examples**: 
  - Matz provides examples illustrating the correct usage of keyword arguments, explaining common behaviors and potential pitfalls when calling methods including keyword arguments. 
  - He clarifies confusing behaviors linked to argument definition, such as how keyword arguments interact with normal arguments.

- **Challenges and Trade-offs**: 
  - Matz discusses the difficulty of maintaining compatibility when introducing changes to the language and addresses concerns over confusing language features versus breaking existing code.
  - He presents three potential future options for managing keyword arguments:
    - Keep the existing keyword arguments as they are, despite their oddities. 
    - Introduce a new structure, such as a 'keyword hash', to clearly distinguish keyword arguments from regular hashes.
    - Fully separate keyword arguments from normal arguments to eliminate confusion.
    - Each option has its pros and cons, mainly around compatibility and usability.

- **Community Engagement**: 
  - Matz asks the audience to express their opinions on the options presented, emphasizing the importance of community feedback in the evolution of programming languages.

- **Conclusions**: 
  - The talk emphasizes the significance of compatibility in language design, avoiding unnecessary breakages that could frustrate users.
  - Matz recognizes that while improvements and innovations in Ruby are necessary, maintaining a stable environment for users is crucial for the language's ongoing success and community support.
  - Ultimately, he encourages the community to explore Ruby’s idiosyncrasies and continues to advocate for a collaborative future that keeps Ruby's spirit alive, stating, "Play with Ruby, find the weird things, keep Ruby weird."

In summary, Mats reiterates that the evolution of Ruby must balance novelty and complexity with user needs, aiming for a sustainable and engaging programming environment.
