vector patterns dispatch on count after dispatching on type

Defect Critical In Progress Unresolved David Nolen David Nolen Fri, 23 Dec 2011 21:41:42 -0600 Fri, 23 Dec 2011 22:22:41 -0600 0 0 Global Rank http://dev.clojure.org/jira/browse/MATCH-36 core.match <p>I was on the fence about this. But after looking at the literature as well as the behavior of condp, I've decided that throwing on unsuccessful match is the way to go. This is particularly important since we put no constraints on the types allowed - we cannot determine exhaustiveness.</p> MATCH-36
