A few years of hobbyist cudding and I've yet to find much use for them outside making of generic special loops, of which every permutation of them have been implemented already by library contributors. LISPs aren't shit so boilerplate code doesn't happen, everything else can be made more tidy with lambdas. Has anyone used LISP's most marketable feature (hygienic or not) for anything at the app level?
