Functional C++ - Gašper Ažman - C++Now 2024
---

The talk runs through the basic elements of functional programming, why we want to do it, and some compositional patterns.

It then switches to explain these concepts on std::optional (the Maybe monad), std::expected (the Error monad), and briefly mentions ranges. It also introduces the validation monad (a kind of std::expected with composable errors) and the Choice monad (and how it differs from std::variant). I really want to extend it to the async monad (std::execution), but I haven't given that part before.

The talk was generally well received, but I want to extend it and deepen it.

A great deal of attention is paid to examples, as I want to impress upon the audience how we can use this programming paradigm together with generic programming in c++, and what kind of support we need from the language to do it well in the future.

The desired outcome of this talk is a newfound appreciation of what c++ can be, how provable the code written in this way becomes, and why c++ can also be a reasonably good functional language, if given the right tools.
