The atomic 'state' doesn't seem to be visible to the datatype methods. The
question is why?
(defprotocol prot-a
(op-a [self x y]))
(let [state (atom 10)]
(deftype t-a [member]
prot-a
(op-a [self x y]
(+ (.member self) x y @state))))
(def t-a-instance (t-a. 5))
This example is in:

Thank you in advance,
