I'm trying to use :or patterns with records but I'm getting an error and 
I'm not sure if I have found a bug (or a  not-implemented-yet) or if its 
the intended behavior (and there are good reasons for it).

Without :or patterns I can do:

(let [x {:a 1 :b 2}] 
    (clojure.core.match/match [x] 
         [{:a 1 :b b}] b 
         [{:a 2 :b b}] b))
;=> 2

I can group 1 and 2 values with :or and do:

(let [x {:a 1 :b 2}] 
    (clojure.core.match/match [x] 
         [{:a (:or 1 2) :b b}] b))
;=> 2

But I'd want to do:

(let [x {:a 1 :b 2}] 
    (clojure.core.match/match [x] 
         [(:or {:a 1 :b b} {:a 2 :b b})] b))

which throws and exception and prints: Unable to resolve symbol: b in this 
context

Is this the way it's supposed to be?

Thanks,

Juan Manuel
