Please critique away, and don't fret about bruising my ego. :-)

Is there a more idiomatic way of getting a warning to show up against the first callee that's not in the current module? I'm not enamored of the monstrosity I'm put together around line 918 of base_events.py (but less enamored about displaying warnings that the user is going to tear their hair out over trying to find the offending source line):
