What's the best way to implement keywords as optional flags to a function? I want to make function calls such as: (myfunction 5) (myfunction 6 :do-this) (myfunction 3 :go-here) (myfunction 2 :do-this :do-that) Using defn, I can define a function such as: (defn myfunction [value & flags] ... ) But the flags becomes a list. I can write my own function to search the list, but such a function isn't included in the core library, so I assume it's not idiomatic. What I'm using now: (defn flag-set? [list flag] (not (empty? (filter #(= flag %) list)))) (defn flag-add [list flag] (cons flag list)) (defn flag-remove [list flag] (filter #(not= flag %) list))
