Well the data is a given set, and the regex pattern is what I'm trying to
develop

Nope

Basically there is a simple regex engine somewhere else that says

if (/$regex/) {print "match"; } else { print "no match"; }

and I need a regex pattern that is the 'NOT the given string' pattern.

So for the given the data set: 'bad', 'soso', 'maybe', and 'good'
I need to be able to say... 'return true if its anything but "good"'.
