Does anyone have sample sizes on Jar file size reduction, or clean compile time from the new backend? I haven't been deep in Scala for a few months, and it sounds interesting that Java8 allowed some improvements on the back end...
2.9 2.10 2.11 2.12
Scala library 9.0 7.1 5.7 5.5
Scala compiler 11.5 14.5 15.5 10.1
ScalaTest (3.0.0) 10.5 10.4 7.0
extremly depending on your use case (p.s. it's not only compile time slower, but -Xminin-forwarders made it way better, but of course bigger jar files), the jar size, too.
