Restarting the discussion. In summary, what Weld/CDI needs is:

1) EJB defers instance creation to an external component
    - Weld deployer provides the hook for instantiating the  components and will:
             a) invoke the applicable CDI constructor of the EJB class
             b) apply decorators on the EJB
             c) *not* apply interceptors on the EJB - for now, this remains a responsibility of the EJB container

2) EJB container provides a hook for preprocessing interceptors after instantiation. The main reason is that EJB interceptors may be CDI-injected

(note: could we reuse the same mechanism as for EJB instantiation, since it boils down to producing an instance of the class? )
