Jozef Hartinger commented on CDI-278:

With Pete and Stuart we discussed that introducing @StatelessScoped might be the right approach for SLSB. This scope would act in two roles:
1.) It would be the scope of a SLSB - implicit for every SLSB so that a user does not have to define both @Stateless and @StatelessScoped on the same class.
2.) For other types of CDI beans @StatelessScoped would guarantee that every method invocation on the bean is executed on a new instance of a given Bean (Bean.create() is invoked for every invocation). That would allow the manager pattern (Solder's @Unwraps) to be used applications.

> 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.
