+1 to [:identifier:] and [:keyword:]. Unfortunately, outside of \i and \k convention is that uppercase means negation (\s and \S, \w and \W, etc.). We can't use that because \I and \K already exist (and \I\i* is a fairly useful pattern).
I'm +0 on \- meaning negation. You'd then have overlap between \S and \-s but I do think it's nice to have a way to match [^[:identifier:]] without resorting to the square bracket negation.
