Common Lisp's macros and grammar go together like bread and butter. A grammar module in the app I built [1] uses macros to generate huge amounts of repetitive code.
Wow, I checked out your ichi.moe app. It's awesome! I'm definitely going to use this as I work on re-learning the Japanese I've forgotten over the years. I've done some Racket and Clojure but never done CL... I'll have to check it out.

I wonder if they're still hiring Lispers. I once passed on the opportunity to work in their Kiev office, but I might give it a shot again.
