 I haven't written out a long example for this, but here's the test case you should be able to discern the meaning from:
 
 ```cpp
-void ToLowerReader(const std::string &name, const std::string &value, std::string &destination)
+bool ToLowerReader(const std::string &name, const std::string &value, std::string &destination)
 {
     destination = value;
     std::transform(destination.begin(), destination.end(), destination.begin(), ::tolower);
+    return true;
 }
