Thanks Simon,
This form is working:
(ns fly.bird)
(defprotocol Fly
(fly [this])
(fly2 [this x]))
(defrecord Bird [nom species]
Fly
(fly [this] (str (:nom this) " flies.."))
(fly2 [this x] (str (:nom this) " flies " x)))
So, we can't define the same method
Try using this for the defprotocol form:
(defprotocol Fly
(fly [this] [this x]))
I don't know whether your defprotocol form is supposed to be allowed.
Either way, better error message(s) would be good.
