>
> The specification currently says that:
> {quote}
> The iterator() method must:
> • Identify the set of beans that have the required type and required qualifiers and are eligible for injection into the class into
> which the parent Instance was injected, according to the rules of typesafe resolution, as defined in Section 5.2.1.
> {quote}
> The ambiguity resolution algorithm as defined in 5.2.2 should be applied.
> 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 
> {noformat}
> @Inject @Any Instance<Common> instance
> {noformat}
> injection point.
> It is clear that instance.get() returns Bar.
> It is however not clear whether instance.iterator() iterates over:
> a) Bar
> b) Foo, Bar
> and whether instance.isAmbiguous() returns:
> a) true
> b) false
