IMO, Scala is a tasteful collection of the best features from a bunch of different languages, including ML, Haskell, Smalltalk, and Clojure. [1] If I taught a survey course of programming language features, such as Stanford's CS 242, Scala is the language I would use to teach it. [1] And they are not transplanted unmodified; often, since Scala has the advantage of hindsight, they are often modified to be even better!
