[Matej Novotny (JIRA)]

    [ https://issues.jboss.org/browse/CDI-733?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13621320#comment-13621320 ] 

Matej Novotny commented on CDI-733:
-----------------------------------

Just for completeness, Weld also has {{Type}} based select on {{Instance}} - https://github.com/weld/api/blob/3.0.SP4/weld/src/main/java/org/jboss/weld/inject/WeldInstance.java#L119-L134

If we want to add this to the spec, please mind the type safety hazard, in Weld we added [this line|https://github.com/weld/api/blob/3.0.SP4/weld/src/main/java/org/jboss/weld/inject/WeldInstance.java#L122] to ensure that things won't blow up (well, at least not as violently). Invoking type-based select on anything else then {{Object}} will possibly result in an error.

> Goal is to enable a bit more meta programming and in particular instantiation of custom parameterized type of events, currently it requires to go through the bean manager whereas the event would be a natural place to resolve an event.
