Hi Steve!
I deleted this post, but still it gets mailed out.
Fixes are in and have been posted already.
See "Reduces Reuse Coupling".
But in any case, thanks. And thanks for the pointer to extend-type. :-)

This is not working for me:
(ns aatree.record-play)
(defprotocol gran
(blip [x y z]))
(defrecord wackel [])
(defn new-wackel [opts]
(let [w (->wackel)]
(into w opts)
(assoc w :blip (fn [this x y z] (+ x y z)
(extend wackel
gran
{:blap (fn [this x y z]
((:blip
There are a several small things here that need fixing:
- in the “gran” section of your “extend”, you’re defining “blap” which is not
part of the gran protocol
- perhaps blip was intended
- the first argument in protocol function declarations refers to the object
itself, often named “this”
-
