I wouldn't be surprised to hear that. I don't think JVM or JVM languages 
are any good for number crunching. Besides that, the Scala implementation 
is probably quite immature at this point since it's so young.

I've only seen how Scala solves problems elegantly. These are from some 
biased blog posts etc. Can you show one example that looks uglier in 
Scala, but looks decent in D or some other language?
