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?
No, he should have told you to use the _1 and _2 from the Boost Lambda library. Bind won't handle the *s. -- Dave Abrahams Boost Consulting www.boost-consulting.com
