Hey Sean, Most of the points in my reply to Roman also apply to `HoneySQL`. In particular this phrase in the README summarises a good deal of my criticism: "When using the vanilla helper functions, new clauses will replace old clauses". You have to go out of your way to get the composability that

Even without reaching for libraries outside clojure.core, there's (update-in m [:key-of-interest] #(if (condition? %) (transformation %) %)) and the ability to convert that into a function, e.g. (defn conditional-update-in [m condition? transformation k] (update-in m [k] #(if (condition? %) (t
