Scala Days 2015 - Functional Programming with Arrows

Yuriy Polyulya presented at Scala Days Amsterdam 2015 Abstract If you’re using a structure that’s very like a monad, but isn’t one, then maybe it’s an arrow. Arrows are a general functional programming technique, popular in Haskell, but so far undeservedly overlooked in Scala. This is a short talk and study case about: functions and syntax extension for arrows arrow type-class what are arrows and how to use them arrows and categories arrows and monads.
