I simplified this as much as possible and it turned into a template 
question, and not a boost question, but I hope that someone here will 
take a second and answer it anyway.  I don't know of another mailing 
list with the expertise of this one in templates.  In the below, the 
inserter for vector<int> is never used, instead, since the vector<int> 
is a type, it matches the simpler inserter for T.  How can I make it 
work the way I want it to?

#include <iostream>
#include <vector>

struct theclass
{
     template<typename T>
     void operator<<(const T& t){ std::cout << "Got a T\n"; }
     template<typename T>
     void operator<<(std::vector<const T> t){ std::cout << "Got a vector 
of T\n"; }
};

int
main()
{
     std::vector<int> vi;
     int i;
     theclass f;
     f << i;
     f << vi;
}
