Scala opened my eyes to functional programming.

Whether that's a killer feature or not is debatable because functional programming has been around for tons of years, even probably more than OOP. 

Howver, from a Java developer perspective, I've seen no other programming language that has done more to promote functional programming than Scala, and that to me is a killer feature.

I'm very glad functional programming is coming to Java, but I hope they don't mess it up like they did with generics.

Even then, the functional programming bits coming to Java are just a fraction of the rest cool stuff that's present in Scala. The best example of this I've found is this:

It's a very funny video too :D

On a more serious note, this is probably one of those arguments where the best we can do is agree to disagree. I'm slightly dissapointed with the final decision you've made, but this is open source development and live goes on…
