Antonin Stefanutti commented on CDI-469:

[~jharting], indeed, I think that's the general idea. Otherwise stated, the need is to be able to have non {{@Dependent}} producer methods depending on the {{InjectPoint}} and somehow have the resultant produced values _cached_ (i.e. the producer method does not get called twice without the active scope) whenever the {{InjectionPoint}} are _equals_, _equals_ being here defined by qualifiers equality.

> Currently, you cannot have a nonbinding producer method, e.g. one where the annotation is read at runtime, with a scope.  This means that repeated injections always happen.  It would be better if you could scope the nonbinding producer methods, so that the results were bound, e.g. to a request scope, so that look ups can be done once.
> The current way to avoid this is to use a holder object with the proper scope.
