commute is passed conj as a function. commute then calls conj messages msg, and sets messages to be the result (which is messages with msg added on) There is a more in-depth example at http://en.wikibooks.org/wiki/Clojure_Programming/Concepts (defn add-employee [e] "add new employee e to employee-records" (dosync (commute employee-records conj e))) commute: At the commit point of the transaction, sets the value of ref to be: (apply fun most-recently-committed-value-of-ref args) ie: (commute messages conj msg) means: messages = apply conj messages msg No closures involved.
