+### pred
+
+`(pred apred)`
+
+Keeps the element only if it matches the supplied predicate. This is the
+late-bound parameterized version of using a function directly in a path.
+
+```clojure
+=> (select [ALL (pred even?)] (range 10))
+[0 2 4 6 8]
+=> (let [p-path (comp-paths ALL pred)]
+     (select (p-path even?) (range 10)))
+[0 2 4 6 8]
+```
+
+### putval
+
+`(putval val)`
+
+Adds an external value to the collected vals. Useful when additional arguments
+are required to the transform function that would otherwise require partial
+application or a wrapper function.
+
+```clojure
+;; incrementing val at path [:a :b] by 3
+=> (transform [:a :b (putval 3)] + {:a {:b 0}})
+{:a {:b 3}}
+```

 ### not-selected?
 
 `(not-selected? & path)`
