That won't work, as passing multiple arguments to any logger function
has a different meaning already:

I'd rather use MDC and a PatternLayout for that:
http://log4perl.sourceforge.net/d/Log/Log4perl.html#4b5b3
If you'd rather like a two-argument function that takes a message and an
error code, you can write a wrapper library around Log4perl that does
exactly that, just increase $Log::Log4perl::caller_depth:
