Good point; it was unclear on my part. What I mean is "on
what part of the pattern did the regex parser fail and
decide that the string didn't match the pattern?" In the
above, the string matches up to the end of the first '.*'
and fails at 'f'. So in my dreamworld, Perl would say, "CSS
parsing failed at

elemName {
	font-fcae: Times New Roman;
}

because there is no property 'font-fcae'."

Is that any clearer?
