How/where C++ namespace std is defined (link to documentation/standard) : <p>This question seems to have been asked many times before but the answers just poo-poo or pee-pee around the issue. I want to find a source in official documentation and standards where this issue is addressed. Apparently, "std" is implied by the files included with #include. Does it mean that there is no explicit "namespace std {...}" anywhere and "std" is like a keyword? I want to know the official definition of this keyword. I want to know how and what is included in "std", everything that is not covered by the definition of a regular namespace with explicit "namespace name"</p>
