Is there a standard C++ function object for taking apart a std::pair?

Question

Does anyone know if there\'s a de-facto standard (i.e., TR1 or Boost) C++ function object for accessing the elements of a std::pair? Twice in the past 24 hours I\'ve wished

Answer 1

From the way you worded your question, I'm not sure this is a proper response, but try boost::tie (part of the Boost::tuple library). It works on std::pairs too.
