The equating of writing slower code to "sloppy programming" seems like sloppy reasoning to me. If it was sloppy to knowingly go with a slower solution, then using Python, for instance, or any scripting language for that matter, would always be "sloppy". It isn't. For me, Scala provides a happy middle ground between a scripting language like Python, and an "enterprise" language like Java. Scala is as nearly performant as Java--and sometimes it performs significantly better than Java due to having parallel collections, and the like--while having nearly the expressiveness of a scripting language like Python. Also, Scala's performance issues are overblown. I program in Scala professionally every day and it performs great.
