I'd quite like to write some Google App Engine apps, but I'm a c# developer by trade, and as such I like static typing and Linq (or at least extensions + lambdas + predicates, if not query syntax). Is there a language I can use on the JVM that offers these features?
Easy to learn, powerful for libs and has full JVM integration. And yes, its readability is amazing (comparing to Java, Scala, C#)!
