Subject: [Boost-users] correct usage of bind

Hi,
Both the statements below bind function buildPair. While the first
works the other fails. What could be a possible fix. Thanks in
advance.
//---- Function to be used by bind -------------------------
template<typename X, typename Y>
std::pair<X, Y> buildPair(X x, Y y)
{
std::pair<X,Y> apair(x,y);
return apair;
}
(std::cout<<buildPair(_1,_2).first<<' ')(1,2); ///--compiles fine---------
(bind(buildPair,_1,_2))(3,5); ///-fails------------
Thanks
sandeep
