Produce clean APIs with algebraic design - Scala/FP tutorial

Jakub Kozłowski demonstrates how to use algebraic design to build clean APIs and domain-specific languages in Scala.

In this video, I'm showing how I use algebraic design, and how it can be applied in both day-to-day programming as well as more rare cases when we're designing more interesting DSLs. While this is barely scratching the surface and admittedly it's not a full introduction to the technique, I hope this will give you a useful tool for playing around with your interface designs.
