Stuart Douglas commented on CDI-129:
------------------------------------

I was actually thinking about this same issue today. IMHO we need a special scope for Stateless and Singleton beans, as they are certainly not @Dependent scoped, and a lot of the rules and restrictions for @Dependent scoped beans simply don't make sense for them. I have created https://issues.jboss.org/browse/CDI-278 for this issue.

> Since @ApplicationScoped currently is defined in 6.5.2 as to be 'like in the Servlet specification' this means that you will get a new instance for every WebApplication (WAR file).
> There is currently no specified CDI scope for providing a single shared instance for a whole EAR.
> We could (ab-)use @Singleton for that, but this is currently not well defined at all.
> Alternatively we could introduce an own new annotation like @EnterpriseScoped or likes.
