Q: logging in realtime

What i want to do is to log some trace massages when *trace-enabled*
flag is set to t.
Due to real time requirements when *trace-enabled* is set to nil
trace code must not be present in function definition.
My aproach is the following:
(defmacro def-some-function ()
`(defun some-function (arg)
(log-to-file *trace-file* (format nil "~A" arg))
changing *trace-enabled* to t and reevaluating (def-some-function) take
the desired behavior but the code to support this is not so clean
Any better ideas?
Thanks in advance.
