I think it would be convenient if one could treat std::pair as a boost two-tuple. Both tuples::tie and tuple assignment already work with std::pair but I've noticed that the get<> accessor doesn't.
So, I propose a simple extension to tuples::get<> with the obvious semantics: boost::get<0>(p) == p.first boost::get<1>(p) == p.second
The trouble with get is that pairs live in namespace std, so if pair get's are not in std, they won't get found by ADL. But if we are willing to live with not having ADL, adding gets for pairs would be fine.
Isn't there another problem? Are references legal arguments for std::pair? -- Dave Abrahams Boost Consulting http://www.boost-consulting.com
