I'm not disagreeing about the complexity, but you can choose to use a sane subset of the language and do away with all the other stuff. You're aware that's the classic counter-argument to "C++ is too complex"? Like with C++, the problem is it will be very hard to agree on what sane subset to use. There are a lot of things nice about Scala, but I can't help seeing it as the C++ of FP languages. Moreover, the Haskell envy it exhibits can be sometimes embarassing.
