The Geekiest Hello World

Folks, I think that I have found (one of) the geekiest hello world out there. Implemented in Groovy using the dynamic interception of method calls. Here it goes:

class Hello {
  Object invokeMethod(String name, Object arguments) {
    System.out.println "hello $name!"

def hello = new Hello()

Which produce the following output:

hello john!
hello you!

I suppose the same mechanism can be used with Ruby (and some other dynamic languages).
