I've been bitten before trying to use (if (some? (thing))) instead of just (if (thing)) for the sake of readability, because as (defn thing ...) evolved, it ended up returning a function call that sometimes returned false instead of just nil, so the conditions were sometimes inverting in subtle ways and it was really hard to track down why.
