> This seamless interoperabiity with Java/JVM is a fairly subtle selling point especially since every JVM language will say they do it. It's only when you try to use them in complex projects and see them fall down that you realise that groovy is the only language that is philosophically trying to be close to Java (I'm fairly keen to try Kotlin to see how that holds up on this count).

Interesting - can you say anything more concrete/specific? E.g. with Scala I've gradually drifted away from a Java-like style over the years, but I found it was very possible to write in a close-to-Java style (e.g. using the Java collections rather than Scala ones, using mutable vars and null and subclasses) when that was what I wanted.
