> When trying to access the property of a outer class from a static inner class the code should fail to compile.
> It doesn't fail to compile when the access happens from inside a @DelegatesTo Closure.
>  
> {code:groovy}
> import groovy.transform.CompileStatic
> @CompileStatic
> class Delegate {
>   static void delegate(@DelegatesTo(Delegate) Closure c) {
>       c.delegate = new Delegate()
>       c()
>   }
> }
> @CompileStatic
> class Outer {
>   String propertyName
>   static class Inner {
>     void someFunction() {
>       // Moving this here results in a compilation error
>       // println(propertyName)
>       Delegate.delegate {
>         // This causes a GroovyCastException at runtime because the generated code tries to access propertyName as if this were a instance of Outer?
>         println(propertyName)
>       }
>     }
>   }
> }
> new Outer.Inner().someFunction()
> {code}
