I was tempted to use yacc, but it turned out the resulting code was not thread-safe and as such did not fit within the context of rsyslog. Also, limited error handling is not a real problem for us: if there is a problem in parsing the configuration file, we stop processing. Guessing what was meant and trying to recover would IMHO not be good choices for something like a syslogd.
