[Boost-users] [bind, tuple] Custom comparison of tuple elements

Assume we have a range of objects of type tuple<T1,T2> and a function 
object that compares two objects of type T1.  How would a person sort this 
range using this function object and bind?  I want something along the 
lines of:

std::sort(first, last, boost::bind<bool>(comp,
   boost::bind(boost::get<0>, _1),
   boost::bind(boost::get<0>, _2)));

but this isn't remotely close to compiling.  I could create a custom 
function object, but I'd rather learn how to use bind properly.

Thanks,
Mark
