Callable Objects in Java, C#, Rust, and C++ - You Are a Parenthesis

Explore the concept of callable objects across multiple programming languages in this comprehensive conference talk from ACCU 2023. Delve into the intricacies of implementing callable objects in Java, C#, Rust, and C++, with a focus on the challenges and solutions specific to each language. Learn how different programming languages approach the implementation of callable objects without relying on operator(). Discover the evolution of Java's transition to lambda expressions, and examine how C#, Rust, and C++ handle similar functionality. Gain insights into a proposed library change for C++ that aims to enhance callable object capabilities. Benefit from the speaker's expertise as an R&D engineer and PL22.16 representative, and understand the practical implications of callable objects in modern software development.
