How do I get ready for C++17?
I have a piece of code which requires C++14.  I want to use something from
C++17 but I also want my code to work now.  So I have
#if C++14 being used
namespace std {
// implement C++ function
}
Don't define those things inside namespace std. Instead:

  namespace boost {
  namespace yours {
  namespace detail {
#if /* C++17 thing available */
      using std::thing;
#else
      /* Define thing yourself */
#endif
  } } }

And then use boost::yours::detail::thing in your library.
