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.
The only reference I found in the archives was a post by Tomas Witt early 2002. "Tuple extension proposal": http://lists.boost.org/MailArchives/boost/msg25582.php
Should I submit the code I've got or does something like this already exist somewhere? (I've tested the code using VC7.1, it doesn't rely on PTS although member-templates)
Please send a patch or code. Jaakko
