Groovy is a JVM language which is dynamically typed (a la python and ruby). It never really took off, partly because you had to understand java (and the JVM) pretty well in order to do anything other than trivial scripts with it. The point being made is that if Spider wants to take off, it had best not require an intimate knowledge of javascript - and we can look to groovy to see what happens otherwise.
