George Gastaldi commented on FORGE-1498:
----------------------------------------

Perhaps we could assume that Comparable instances could be automatically ordered in the Imported.iterator(). Then it could be up to the implementation to decide which strategy to use for ordering. WDYT?

-------------------------------------------

Ah, so you're saying that you want the listeners to be ordered? Do we ever
need to execute them in order? If so, we should add a priority() method
and/or make them Comparable/Provide a comparator.

> Some services may require to be executed before others. It would be nice if the container could order these services while an iteraction of an {{Imported}} object happens. This ordering may happen based on an annotation or an interface.
> Eg: When an {{UIContextListener}} is returned from an {{Imported}}, the {{CommandScopedContext}} should be fired first, to allow {{@CommandScoped}} objects to exist before other UIContextListeners are fired.
