In the talk titled "Ruby Rendezvous: Method Calls, Procs, and Beyond," Agnieszka Małaszkiewicz discusses various interesting and lesser-known features of the Ruby programming language, specifically focusing on method calls and the use of procs.

- **Introduction and Background**: Agnieszka expresses her gratitude to the audience and organizers while sharing her nostalgic connection to the Ruby community, having started with Ruby in 2011 or 2012.
- **Title Inspiration**: The title of the presentation, crafted with help from AI, encapsulates its focus on Ruby methodology and procs without sounding overly technical.
- **Ruby Updates**: Agnieszka shares changes in Ruby since her previous talk, demonstrating features that still exist in modern Ruby versions, such as string manipulation techniques.
- **Method Calling Strategies**: She highlights various methods to call a method in Ruby, inspired by Greg VTech's article on twelve ways to do so, and she discusses the scope resolution operator (double colons) as an interesting method calling strategy. Agnieszka emphasizes the rarity and specificity of this method of calling methods.
- **Procs in Ruby**: Agnieszka defines procs as encapsulated blocks of code essential for functional programming in Ruby, detailing various ways to invoke them (using `call`, `yield`, and square brackets).
- **Triple Equal Sign Usage**: A unique aspect discussed is the triple equal sign for calling procs, highlighting its historical context and reliability from older Ruby versions.
- **Comparative Examples**: She provides examples of calling methods with and without arguments, demonstrating how the `to_proc` method works with symbols and hashes. She illustrates the concept of currying, which allows partial application of functions, enhancing the flexibility of proc usage.
- **Ampersands and Maps**: The presentation explores how using ampersands can simplify the use of procs with the `map` method, and discusses the limitations of this approach when working with additional arguments.
- **Conclusion**: Agnieszka concludes by summarizing the various methods to call methods and procs in Ruby, emphasizing the enjoyment and complexity of these techniques, while mentioning that some may not be production-ready solutions.

Overall, the talk reflects a deep understanding of Ruby’s functionality, aiming to arm developers with knowledge of advanced features that can enhance their coding practices.
