    // now...define the class separately on its own in one script...
    // HERE'S and AWKWARD BIT.........
    // YOU HAVE TO END WITH: null;
    // ....OR ELSE YOU GET:
    // javax.script.ScriptException: javax.script.ScriptException:
    // org.codehaus.groovy.runtime.metaclass.MissingMethodExceptionNoStack: No signature of method: c.main()
    // is applicable for argument types: ([Ljava.lang.String;) values: [[]]
