Hi,
I found this old post:
http://groups.google.com/group/clojure/browse_thread/thread/45e118a638a5af8e/02eab5ae0d9023ff?lnk=gst&q=binding+destructuring#02eab5ae0d9023ff
And was wondering what is the status of Stephen's patch?
Is there a reason why clojure/binding does not support destructuring

Hello Stephen.
I am not sure I understand.
Rich,
This is code from my socket repl that sparked my interest in support
for destructuring in clojure/binding.
(defn socket-streams ;; returns a vector of 3 streams

user=> (binding [[a b] [1 2]] (+ a b))
java.lang.ClassCastException: clojure.lang.LazilyPersistentVector
cannot be cast to clojure.lang.Symbol (NO_SOURCE_FILE:3)
