> Method pointer expressions are not type checked (with STC enabled). The following example should not compile for a number of reasons:
> {code}
> @groovy.transform.TypeChecked
> void test() {
>   def x = 'abc'.&bar //bar is not a String method
>   x() // groovy.lang.MissingMethodException
>   x = String.&length //length is a non-static method
>   x() // java.lang.IllegalArgumentException: object is not an instance of declaring class
>   x = String.&size //size is a non-static extension method
>   x() // java.lang.ClassCastException: java.lang.Class cannot be cast to java.lang.String
> }
> test()
> {code}
