The Scala programming language is under 10 years old (I believe it was originally released in 2001) and could be claimed to be the first:
- Real-world scalable language (e.g. from scripts and implicits to actors and modules). I'm saying real-world because some will claim others, starting with Lisp, were first here, but I believe Scala's Java compatibility, object-oriented features, type system etc. make it different
- Real-world fusion of functional and object-oriented programming (e.g. having higher-order functions, but also state and static typing). I'm saying real-world again because while e.g. Oz is older, I believe Scala's compatibility and pragmatism make a difference
