The question that arises is whether the implementation should apply ambiguity resolution algorithm as defined in 5.2.2 or not.
This is explicitly required for get() but is not required for iterator(). This causes the following inconsistency:
Assume two classes Foo and Bar which both implement common interface Common. Bar is an enabled alternative.
Assume further the following
@Inject @Any Instance<Common> instance
It is clear that instance.get() returns Bar.
It is however not clear whether instance.iterator() iterates over:
b) Foo, Bar
and whether instance.isAmbiguous() returns:
