That's a very useful set of features, glad to see more of the features I'm used to in Scala (although obviously not the first to have those features) showing up in C#. It's still a bit of a stretch to say that C# has "overtaken" Java in general, or to read too much into Microsoft's moves (they haven't open sourced any of their main profit-generating software (SQLServer, Windows etc.), just enough to earn a bit of street cred. amongst developers). In terms of features C# is far ahead of Java, but many Java developers simply don't care as C# is far from being widely established and broadly used outside of Windows. Even on the JVM many Java developers will use Java the language as it's the standard, rather than because it is a fantastic language. Those who do care have moved on to Scala, Clojure etc. We've relegated Java (the language) largely to legacy status, but rely heavily on the Java ecosystem (JVM, IntellJ, java libs etc.).
