Yeah exactly, this is why I stopped liking DSLs about 15 years ago, shortly after using Ruby extensively (probably not a coincidence) and converting to Clojure, where there was a large movement away from macros despite it being lisp. They're good in very isolated situations, and only when designed very carefully. This wm is quite possibly one of them; if you need more complexity than the macros here allow, and adding/changing macros only makes it worse, just use another wm.
