I agree Scala is very powerful. I said messy because it is "too powerful", added too many features. I think this is their mistake. I respect the community, but can show my opinion as you can about java.
I really don’t feel that Scala has too many features. It is a relatively small language which is very elegant due to having almost no edge cases. Sure, due to not having many features yet being very expressive it has to have very powerful language primitives that can be abused, but I really don’t think that it is as bad as its name.
Java is also a messy language and the reason for a lot of the mess in Scala. If you want elegance, then you should probably learn something like Haskell.
