While I agree with the general point of using best practices in code samples, the Cpp Core Guidelines actually encourage[0] using using namespace std; for std specifically, giving the reasoning that: > sometimes a namespace is so fundamental and prevalent in a code base, that consistent qualification would be verbose and distracting.
