The author explicitly states terseness is a goal, and compares alternatives' overhead to bash. However, he recognises there is a limit whilst remaining safe/close to Scala. I don't agree control structures are a major problem. There are subtle differences between correct and incorrect expressions, and they are not checked at "compile" time.
