 Description   

All three of these expressions should work (according to @dnolen in IRC):

user> (match/match [5] [((:or 5 6) :as x)] x)
CompilerException java.lang.RuntimeException: Unable to resolve symbol: x in this context
user> (match/match [5] [(:or (5 :as x) (6 :as x))] x)
5
user> (match/match [5] [(:or (5 :as x) (6 :as y))] x)
CompilerException java.lang.RuntimeException: Unable to resolve symbol: x in this context

(The first makes sense to me, but the latter two don't; e.g. should y be nil in the last example, or something else?)

Though it's not necessary, it'd be nice if the following "sugared" form worked, too:

user> (match/match [5] [(:or 5 6 :as x)] x)
CompilerException java.lang.RuntimeException: Unable to resolve symbol: x in this context
