This convenient feature of the STL has wreaked havoc -// on MFC and as a result Microsoft punted and said "use the std namespace." -// However, this introduced a new problem -- the STL can no longer -// automatically derive !=, <, >=, and <= from the objects' existing -// operators, because the operators are not accessible from the std -// namespace (they are in the global namespace). In fact, STL cannot -// even find the default global operators (such as == between two -// classes). This seems like a bug in Microsoft's compiler. -// -// If you are storing a new class of objects in an STL container and -// want to use find() on the container, then you must declare a global -// equality operator on the object.
