Description

The way destructuring happens should not be affected by the fact that I have the same w at two-levels.
user>> (let [{{a :a b :b :as w} :c a1 :a b1 :b :as w} {:a 10 :b 20 :c {:a 30 :b 40}}] {:a a :b b :b1 b1 :a1 a1})
{:a 30, :b 40, :b1 40, :a1 30} <- unexpected behaviour.....

user>> (let [{{a :a b :b :as w} :c a1 :a b1 :b :as w1} {:a 10 :b 20 :c {:a 30 :b 40}}] {:a a :b b :b1 b1 :a1 a1})
{:a 30, :b 40, :b1 20, :a1 10} <- expected behaviour ..

Even having the :as things from both should not affet how others are destructured.. The email thread talking about the same is here
