Eric Milles updated GROOVY-10476:
---------------------------------
Description:
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}
