Mark Struberg commented on CDI-278:
-----------------------------------

@StatelessScoped imo is contradicting itself. The most important fact about any NormalScoped bean is that it has a well defined lifecycle. So it for sure cannot be NormalScoped. But it would be perfectly possible to treat it as JSR-330 @Scoped. We don't need to introduce an own annotation for that imo.

Solders @Unwraps is just a workaround for a deficit of CDI Contexts. I think I have discussed that already with Pete and Stu and we came up with something like adding destroy(Bean<?>) to a new DisposableContext extends Context interface.

Invoking Bean#create() for every invocation is frankly said crazy. Think about recursive invocations, etc. a->b->a ... That would end up in an endless loop! It would also be a performance nightmare.

> At the moment Stateless and Singleton beans are classified as @Dependent scope by default, which is not really very useful, as a lot of the rules for dependent scoped beans simple do not apply to them (they violate pretty much every rule for dependent scoped beans in 6.4).
> I think we need to define a new scope for these beans, or at least clarify their behaviour when they are @Dependent scoped.
