TXR has regexps is you need them. The regex engine is geared in a different direction from mainstream regex: it doesn't have anchoring, register capture or Perl features like lookbehind assertions. On the other hand it has intersection and negation (without backtracking).
TXR translations of Clojure, Common Lisp and Racket solutions to the same problem:
Maybe a few examples of "data munging" tasks which the authors view as poor fits for [language X] and how their stuff solves the problem better.
Maybe something like "why is our language better than regexps in whatever language environment you already know?"
