A big moment for Scala. I've used it professionally for 5 years and am still in love with it. The expressiveness, the power, everything about it is a joy. This just takes it to another level by removing a few warts and simplifying it whilst adding some amazingly useful new features. A really tricky balance needed to be struck. I think they've pulled off an unlikely and amazing feat with this release.
