I agree that such a thing would be helpful. One way to solve it is to
make the main logging procedure a special form, which then only
evaluates most arguments when the severity argument is low enough.

On the other hand, SRFI 215 says that it is a middle-level logging
system, so the above functionality could also be implemented at a
higher level that builds upon this SRFI.

As such, it's desirable for logs to not only be not printed when that level of logging isn't enabled, but for its message / data to not be even calculated or allocated (http://www.slf4j.org/faq.html#logging_performance). I don't have a strong opinion on how this should be implemented, but I think it's a point that is definitely worth thinking about in this srfi.
