A language can be both static and dynamic. C# introduced the 'dynamic' keyword, and perhaps they'll go further with that idea in the next version. The Java 7 JVM will have the 'invokedynamic' instruction, plus a new Java API to manage it. Perhaps Scala will extend the language syntax at that time to allow dynamic typing, with that API underneath, for those few cases where dynamic typing's better. A language that was dynamic first, then added the static, is Groovy and Groovy++.
