What's the use case for this?
(def one? #{1})
(def two? #{2})
isn't much worse. I suppose a macro to emit those might be useful,
though I'd probably put the fn-names first in each pair; something
like
(defmacro specific-thing-preds [& kvs]
`(do ~@(map (fn [[k v]] `(def ~k #{~v})) (partition 2 kvs))))
(specific-thing-preds one? 1 two? 2)
