The opinions about Scala in the Haskell community differ widely. Most will immediately point out reasons why they think Scala is complex and that Haskell is so much better. But is it really? In this talk, we will take a radically different approach: We will outline what Haskell can learn from Scala and depart from the usual narrative that it is just a “lesser Haskell for the JVM”. Topics will include dependent types and computations at the type level, composability and modularity, and compile-time reflection and generic programming. We will also compare and contrast the appearance of several popular “design patterns” in Haskell and Scala. If you’re interested in hearing about “Hasochism”, “shapeless”, and how to make the Scala compiler cry, you should definitely attend this session.

What Haskell can learn from Scala

Lars Hupel

Lars is a PhD student in Munich, Germany, working in the area of theorem proving. He has been using Scala for quite a while now, and is known as one of the founders of the typelevel initiative which is dedicated to providing principled, type-driven Scala libraries. He also talks about Haskell and Isabelle a lot.

Miles Sabin

Miles has been doing stuff with Scala for more than ten years, currently with Underscore Consulting. He is a cofounder of Typelevel and his best known project, the Scala generic programming library shapeless, is the weapon of choice wherever boilerplate needs to be scrapped or arities abstracted over.
