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 atom. To pass
the value you would deref it with '@' -> #(foo % @changeling)
