+        List_Random
+
+    Description:
+        Randomly select items in a list [2021-04-24]
+
+        If a list has 3 elements, this generates a random int
+            in the range [0-2] (inclusive), then returns list{i}
+
+    Alias:
+        python uses the name: random.choice( <list> )
+
+    Example:
+
+        List_Random( {"Dog", "Cat", "Fish"} )
+        // returns: "Cat"
+
+    future:
+        - [ ] validate empty list, or null, or null in list
+        - [ ] nicer user-facing errors
