I'm glad you enjoyed the topic! 

Regarding your suggestion it's a very good one. Scala is also one of the languages that is in my "~~should check~~" list, specially because I have a friend that is currently doing heavy developing in Scala and he's always saying good things about it! :-)

So, I guess it's a possible post, the hard part is to understand what should be compared between those three languages. Even though comparing performance is always intesting, I'm sure that there are other interesting metrics interesting to watch (and you probably have some in your mind since you mentioned ~~several levels~~). ;-)
