Thread: using s specific namespace in all class members, using directive in class header

Hi everyone, I have some memory that it was possible to write something like this:

Code:

class MySpecialClass
{
public:
    using namespace boost;
};

And then was boost namespace visible in all member functions of that class, but of course have I forget exactly how to write it. What is the right syntax to accomplish this? I have been started to get tired of written using directive in every member function

Thanks in advance.
