Applicative - The Forgotten C++ Functional Pattern

Explore the often-overlooked applicative functional pattern in C++ through this comprehensive conference talk from CppCon 2023. Delve into the power and utility of applicatives, understanding their significance beyond monads and functors in functional programming. Learn how applicatives can simplify and enhance code composition across various C++ concepts, including optionals, expected values, ranges, futures, parsing, validation, error handling, transforms, and functions themselves. Gain practical insights into implementing applicative interfaces, with numerous code examples and no complex category theory. Discover how this pattern can lead to more elegant, composable, and maintainable C++ code, potentially reshaping your approach to monads and functional programming in general.
