So what you mean is not "the warning can be turned off by using (message "%s" )" but rather "the warning can be turned off by using (message +)" Namely: warn if we use a _single_ non-constant expression as argument, but don't complain if we use more than one expression as argument. I'd consider that a good idea, but I find it hard to gather this as your proposal from the wording you used. -- David Kastrup, Kriemhildstr. 15, 44793 Bochum
