I really wanted to like Scala, I came to the language looking for a Haskell on the JVM, but then just found it sacrificing too much, mainly for Java compatibility.
The close compatibility with Java does allow an easy transition for Java developers, but it's a transition to writing what it repeatedly deemed unidiomatic Scala by the Scala community. And then I've seen the same community scoff at unenlightened Scala developers that are writing "Java++".
Half of Scala could make a really nice language, but the complexity of the full thing is not something I want to work with again.
You call it sacrificing, I call it awesomeness. Scala achieves the best marriage between OOP and FP available. If you come from Haskell, you can view that as a sacrifice, of course. But I don't, to me that's a strength.
Scala is not Haskell and Haskell is not Scala. If you use one and expect the other, you'll be disappointed.
