I added a comment <http://dev.clojure.org/jira/browse/CLJ-979?focusedCommentId=37843&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-37843> in CLJ-979, I believe I have a case which is broken by the change in delegation order, if I'm correct in my understanding of what the CLJ-979 change is actually doing.
