`partial` won't work here because you're partially applying *two* arguments, `type` and the :idVe portion of the &rest args. `partial` only lets you override an *unbroken* sequence of args at the *beginning* of the arglist. For instance, (partial log "DEBUG" "default message") would work. To override some of the &rest args, you need to use `apply`:
user=> (defn debug-com [msg & args] (apply log "DEBUG" msg :idVe "COM" args )) user=> (debug-com "message") LOCAL: DEBUG -> message <- COM nil user=> (debug-com "message" :id "REMOTE") REMOTE: DEBUG -> message <- COM nil If it really needs to be an anonymous function, `fn` works with the same syntax.
