[cdi-dev] Accepting class type for simple (qualifier) annotations in APIs?

Just a naive remark regarding Instance of annotations without members. I already used a lambda to have such an instance:

BeanManager.getBeans(MyBean.class, () -> MyQualifier.class)

I’m not sure there are no problem by using this short cut, but it is quite convenient.
