(defmacro defthingyfn [name arglist & body]
  `(defn name ~(vec (cons '{:keys [thingy mumble fiddly]} arglist)) ~@body))

(defthingyfn foo [x]
  (...thingy ... mumble ... fiddly ... mumble ... mumble ... x ... thingy
...))

(defthingyfn bar [x]
  (...mumble ... thingy ... mumble ... mumble ... x ... thingy ... fiddly
... thingy ...))
