Hi all,
Suppose I have the following function:
(defn foo [x changeling]
(cond
(= (first x) 'bar)
(map #(foo % changeling) (rest x
(def foobar (atom {:something "in-here"}))
Now, changeling gets bound to (atom {:something "in-here"}). The
conditional in foo might contain another ca
Not sure if I understand your question/problem but, this:
"How can I avoid the binding of changeling to the initial value of the
atom and have the anonymous function passed to map use the current
(possibly changed) value of changeling? "
You are binding a reference not the actual value of the ato
Now that I've read your e.g. a couple more times you seem to want to
change the value of atom in foo.
So first since you def the atom, there is no need to pass it to foo.
Second when trying to see the value of the atom you deref it with @
