Np, So if I understand it right. I see the first one in repl.
Because midje has #{octavia} and in another function is stated :
(def octavia {:name "Octavia E. Butler"
:birth-year 1947
:death-year 2006})
clojure makes from the first {octavia} the second {:name "Octavia E.
Butler" :birth-year 1947 :death-year 2006})
so that is why there are both the same.
