Hi Matthias, I can't disagree with you, and am open to change my mind. Just
a question. Given again this example:
(ns protocols)
(defprotocol P (get [_]))
(ns app)
(defrecord R []
protocols/P
(get [_]
42))
(can you call R's get without resorting to dot-notation, this is, with a
namespace qualification instead? I couldn't achieve it - perhaps I'm
missing something.
