But I can do it with Boost::Bind: std::sort(vec.begin(), vec.end(), boost::bind(std::less<int>(), *_1, *_2));
This looks new to me. What exactly does this do? Sort the container of pointers by applying std::less to the pointees?
Boost::Bind's solution is much better that yours, because it constists indirector_unary, indirector_binary, indirector_ternary and so on.
Read boost::bind documentation http://www.boost.org/libs/bind/bind.html.

That doesn't work for me. std::sort(vec.begin(), vec.end(), boost::bind(std::less<int>(), *_1, *_2)); deref.cpp:154: error: no match for 'operator*' in '*<unnamed>::_1' deref.cpp:154: error: no match for 'operator*' in '*<unnamed>::_2' Am I missing something? -- Matthias Kaeppler
