For future enhancements one can consider creating a global object that provides functions like gr_debug(), gr_error(), gr_warning() that are accessible by both blocks and applications. Similar to what is available in Qt. I guess the only advantage over fprintf's would be uniform management errors and debug messages that could provide controlled shut down in case of critical errors.
