(defn some-map [m] (remove-vals m nil?))

some-map builds on top of remove-vals to provide a really quick way of filtering maps out of nil values. It is named some-map because in Clojure there is some? function which returns false only if the argument is nil.

(some-map {:flower "red", :apple "green", :fabric nil})
=> {:flower "red", :apple "green"}

(some? nil)
=> false
