> Follow up from GROOVY-8133.  Using a {{Stream}} or other iterable-like type (provides {{iterator()}} method but does not implement {{Iterable}}) in a for-each loop works but does not provide type inference beyond {{Object}} for the loop element type.
> Consider the following:
> {code:groovy}
> @groovy.transform.TypeChecked
> void test() {
>   for (e in ['a','b','c'].stream()) {
>     println e.toUpperCase()
>   }
> }
> {code}
