Thank you for the explanation.

Perhaps this is similar to the "where do I customize swap()?"
question, but one could argue that this overload should live in the
std namespace, where the least specialized template function was
declared. After all, it's std::operator<<() that we're overloading,
not MyNamespace::operator<<(). We're trying to introduce special
behavior for a particular argument type, not change the basic protocol
of the template function.
