-// Google Test defines the testing::Message class to allow construction of
-// test messages via the << operator. The idea is that anything
-// streamable to std::ostream can be streamed to a testing::Message.
-// This allows a user to use his own types in Google Test assertions by
-// overloading the << operator.
-//
-// util/gtl/stl_logging-inl.h overloads << for STL containers. These
-// overloads cannot be defined in the std namespace, as that will be
-// undefined behavior. Therefore, they are defined in the global
-// namespace instead.
-//
-// C++'s symbol lookup rule (i.e. Koenig lookup) says that these
-// overloads are visible in either the std namespace or the global
-// namespace, but not other namespaces, including the testing
-// namespace which Google Test's Message class is in.
-//
-// To allow STL containers (and other types that has a << operator
-// defined in the global namespace) to be used in Google Test assertions,
-// testing::Message must access the custom << operator from the global
-// namespace. Hence this helper function.
-//
-// Note: Jeffrey Yasskin suggested an alternative fix by "using
-// ::operator<<;" in the definition of Message's operator<<. That fix
-// doesn't require a helper function, but unfortunately doesn't
