Well, to add things like Named in Qi4j you would rather do it by simply
having the Composite extend that interface:
interface MyComposite extends Named, Composite {}
This is just basic Composite Oriented Programming, and is not a feature
but a principle.
If you don't like having to add "Named" everywhere, I suggest doing a
base interface which acts sort of like a pointcut:
interface DomainObject extends Named {}
interface MyComposite1 extends DomainObject, Composite {}
interface MyComposite2 extends DomainObject, Composite {}
If you now want to add ACL to all DomainObjects, change it to:
interface DomainObject extends Named, ACL {}
and both Composites will get it.
This gets you very very far.
We have, however, also talked about doing more dynamic mixin additions,
in the thread about @Abilities, which solves point 2) in his blog post,
as there can then be two methods with the same name, but since they
belong to different interfaces they will do different things.
I would like to also note that @DeclareMixins("SomeC*") is rather
horrible. If you refactor SomeClass to AnyClass it will all of a sudden
not be Named anymore. Yeuch...
