 In many cases, it may be useful to return a specific, user-defined "Value or error" type.
 For example:
 
-    struct
+    struct Distance {
+        int value;
+        int unit = 1;   // 1 mens meters
+    };
+
+    Distance d1 = measure(obj1);    // access d1.value and d1.unit
+    auto d2 = measure(obj2);        // access d2.value and d2.unit
+    auto [value, unit] = measure(obj3);   // access value and unit; somewhat redundant to people who know measure()
+    auto [x,y] = measure(obj4);     // don't; it's likely to be confusiong
 
 The overly-generic `pair` and `tuple` should be used only when the value returned represents to independent entities rather than an abstraction.
