should "using namespace std" be used?

Pep
Is it best to include the code "using namespace std;" in the source or
should each keyword in the std namespace be qualified by the namespace tag,
such as

std::cout << "using std namespace" << std::endl;

Myself I am not sure which I prefer, it is certainly easier to specify that
the std namespace is being used instead of tagging each member of the
namespace?

There is still the risk that new names are introduced in namespace
std in
the new standard conflicting with a heavily used name in your
project.

I consider this risk however to be fairly small since new names will
very
likely be mostly introduced through new header files thus not
affecting
existing code.


Right now new features are being added to existing headers in the
draft for the next standard. New features in their own headers, like
type_traits, are likely to be used by other parts of the standard
library, thus included indirectly.

I consider the risk to be fairly LARGE.

On the book <Generic Programming and the STL>( Matthew . H . Austern ),this function is defined as iterator set::begin() const. However, why should a const object returns a non-const iterator?

I tried to read the source of GNU STL(version 3.4.1).They were using a red-black tree to implant it (std::set has a...
