Perhaps what we need is a proper logging infrastructure? The above message could be flagged as a 'debug' level message. stdout/stderr would only get to see the 'info' or higher level messages, the rest would be logged only to syslog, keeping the user interface clean. I know such a logging mechanism exists in Guile-Lib, as the (logging logger) module [0]. What do you think? Thanks, Maxim [0] https://www.nongnu.org/guile-lib/doc/ref/logging.logger/
