      Description

      With the class definition, it appears to produce the correct output:

      @groovy.transform.CompileStatic
      class Foo {
        static void main(args) {
          Function<String, String> lower = String::toLowerCase
          println "lower = $lower" // => Foo$$Lambda$14/0x0000000801205040@7bd4937b
        }
      }
      

      Removing to make it a script method gives:

      @groovy.transform.CompileStatic
      //class Foo {
        static void main(args) {
          Function<String, String> lower = String::toLowerCase
          println "lower = $lower" // => org.codehaus.groovy.runtime.MethodClosure@4cdd2c73
        }
      //}
      

      I don't know whether it is a gap in method reference handling or does the @CompileStatic annotation get lost on the special script main method when we override. Still to be investigate but we either need to fix or document.
