Brian,

Woah - so the JVM/java now has anonymous classes?  Could this be 
exploited for a form of type-safe "multiple return values/tuples" 
similar to what C# offers? Similar to whats shown in 
http://stackoverflow.com/a/11795087 ?

If that was exposed with similar syntax in JDK9 that would be awesome.  
Would play nice with Streams, lambdas and more....
