Yeah,  namespaces intend, is, as said,  have a clear distinction between=20
functions of different vendors, etc which can be named the same way, and=20
your own code can have the same problems, so the recommended (and the=20
best) is avoid this kind of general declaration of a namespace (this=20
phrase is of mine, not from any book) , so the recommended is use=20
namespace_name::variable(orfunction) and simply variable(orfunction) for=20
those you are declaring yourself. Or, if you're lazy, you can use that=20
declaration for individual functions or variables from the namespace you=20
know that there will no other with the same name you want to use, as
using namespace  std::cout;
using namespace std::in;

If you don't want use namespaces the rigth way, the best is include the=20
.h versions, which don't declare namespaces, but are considered=20
deprecated and probably (?) they won't be supported in the future, as=20
said in my original answer.
