Capabilities are an exciting development for the future of Scala, but are still misunderstood and a little abstract.

The purpose of this talk is to introduce the problem they are trying to solve and, step by step, demonstrate how they can be used to encode effects while allowing developers to use a direct style of programming.

By the end of the talk, we’ll have created a respectable set of effects and their handlers, and written an entire program using them to demonstrate how natural that style of programming can be.
