I guess Scala being "the most expressive typed language on the JVM" is true in the sense that it has a ton of features (OOP, FP, Exceptions, null Java backwards compatibility, etc.), but that's just too many features for a coherent language.
It's funny that both java & c# seem to be picking up many scala features in their latest & future versions like traits, lambdas, tuples, pattern matching, case classes, closed hierarchies, declarative generics...
Your language isn't incoherent if you can build features on top of each other with is exactly what scala does.
