>             Project: Groovy
>          Issue Type: Bug
>            Reporter: Paul King
>            Assignee: Paul King
>            Priority: Major
>             Fix For: 4.0.0-alpha-1, 3.0.6

> With the class definition, it appears to produce the correct output:
> {code}
> @groovy.transform.CompileStatic
> class Foo {
>   static void main(args) {
>     Function<String, String> lower = String::toLowerCase
>     println "lower = $lower" // => Foo$$Lambda$14/0x0000000801205040@7bd4937b
>   }
> }
> {code}
> Removing to make it a script method gives:
> {code}
> @groovy.transform.CompileStatic
> //class Foo {
>   static void main(args) {
>     Function<String, String> lower = String::toLowerCase
>     println "lower = $lower" // => org.codehaus.groovy.runtime.MethodClosure@4cdd2c73
>   }
> //}
> {code}
> 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.
