Bake Real-life Apps with a Handful of Free, Coproducts & Types

" summary

A presentation about applying Free monads in real Scala applications: it explains the motivation for using Free, Coproducts and algebraic types to decouple business logic from execution, and shows how to build a realistic app using the Freek library. It also covers potential limitations, future directions, and recent scalac improvements that simplify this approach, with some additional example cases if time allows.
