+// current compiler.

+// The VN_HAS_RANGE_LOOP define indicates if the compiler supports range based
+// loops.

+// HACK: Currently not checking the compiler and defaulting to no range loop support.

+// operation for STL items.

+//     _receivedResponses.swap(empty);
+// #else

+// using an initialization list to initialize STL containers.

+// [Example]

+// #if VN_SUPPORTS_INITIALIZER_LIST
