> Consider the following:
> {code:groovy}
> @groovy.transform.TypeChecked
> void test() {
>   def list = ['a','b']
>   for (item in list.iterator()) {
>     item.toUpperCase() // Cannot find matching method Object#toUpperCase()
>   }
> }
> {code}
> Inferred type of "item" is {{java.lang.Object}}.  Without ".iterator()" it is {{java.lang.String}}.
