Clojure: destructuring map without naming key

Source: Destructuring map of map with unknown keys

1 2	user> (let [[[k {:keys [pim pam]}]] (seq {:basic {:pim 2 :pam 3}})] [k pim pam]) [:basic 2 3]

But no need of seq if we iterate with for.

1 2	user> (into {} (for [[k {:keys [pim pam]}] {:basic {:pim 2 :pam 3} :simple {:pim 20 :pam 30}}] [k {:pam pim :pim pam}])) {:basic {:pam 2, :pim 3}, :simple {:pam 20, :pim 30}}
