Answer 1

The behavior you are seeing is expected since the quit-dr function throws an exception when called. This is the source for quit-dr taken from here.
(defn quit-dr [ & form]
(reset! element (first form))
(throw quit-dr-exception))
According to what the README shows you should quit the debug-repl by evaluating the empty list ().
