Scala 2.12 is moving to Java 8, which brings a more streamlined way to compile closures, as well as default methods -- a poor man's traits (Scala's lightweight approach to multiple inheritance). We're very eager to emit more efficient code using these new VM features, and to upgrade our Java interop, so that Java 8 programmers can more easily use Scala libraries and vice versa. To make the most of this upgrade, we have to go all-in, as I'll explain in this talk. To ease the transition, most features destined for 2.12 will come to the experimental side of 2.11.x first. We'll also make sure to make cross-building seamless by providing full source compatibility between 2.11 and 2.12 (including deprecated methods). [Our roadmap](http://scala-lang.org/news/2.12-roadmap) has more details. This talk will provide a high-level comparison between Java 8 and Scala (and I'll tell you why I believe Java 8 will spur on Scala adoption). We'll also go on a whirlwind tour of the compiler internals, to see how our implementation takes advantage of these new Java 8 features.

I lead the Scala team at Typesafe. Before that, I spent most of my PhD and post-doc hacking the Scala compiler (I implemented type constructor polymorphism & inference, integrated dependent method types and type inference, and rewrote the pattern matcher from scratch in 2.10).

In my spare time, I eat food, drink coffee, practice yoga and travel (flaneur-style).
