LISP macros in practice

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?

Macros are not a replacement for inlining functions (you can declare a function to be inlined in CL), and it's bad form to use macros for that purpose. Their purpose is completly different.
