Re: Template instantiation context

  Assume we have these three files:

//--------------------------------------------------------------
// foo.hh
#include <iostream>

template<typename T>
void foo(T value)
{
    static int s = 0;
    ++s;
    std::cout << "value:" << value << ", s:" << s
              << ", externalVar:" << externalVar << std::endl;
}
//--------------------------------------------------------------

//--------------------------------------------------------------
// bar.cc
namespace { const int externalVar = 456; }
#include "foo.hh"

void bar()
{
    std::cout << "In bar(): ";
    foo(200);
}
//--------------------------------------------------------------

//--------------------------------------------------------------
// test.cc
namespace { const int externalVar = 123; }
#include "foo.hh"

void bar();

int main()
{
    std::cout << "In main(): ";
    foo(100);
    bar();
}
//--------------------------------------------------------------

  Now we compile test.cc and bar.cc into an executable program. What
should be the output of this program?
