-Some common, idiomatic aliases are shown below:
+As noted in the next section, it's generally considered idiomatic to use
+an alias that is the last segment of the namespace, if that makes it unique,
+or else the two segments, typically dropping redundant parts like `clj` or `core`.
+
+Amongst Clojure's core and Contrib namespaces, the following namespaces have
+idiomatic aliases following that pattern:
 
 |===
 | Namespace | Idiomatic Alias
+| clojure.datafy
+| datafy
 | clojure.edn
 | edn
 | clojure.java.io
 | io
-| clojure.java.shell

+Then there are some core and Contrib namespaces that have shorter idiomatic aliases:

+| mat
 | clojure.tools.logging
 | log
+| clojure.core.reducers
+| r

+
+And amongst commonly used community libraries, there are also many that have
+widely-used, idiomatic aliases for several namespaces:

 It's clear that the one thing they have in common is that they aim to be concise, but still carry some meaning (aliasing `clojure.walk` to `w` would
 be concise, but won't carry much meaning).
