Hello, All!

I write example code for tuples::tuple::get use tuples::tie.
If compile icl (Intel C++) v 7.1 or bcc32 (Borland) v 5.6.4 all ok,
but if compile g++ (GCC) v 3.2.2 or cl (MSVC) v 13.00.9466 - i have eror.
;-c
I need to use it in MSVC.
Help me!

========tie.cpp========
#include <iostream>
#include <boost/tuple/tuple.hpp>

using std::cout;
using std::endl;

template <int num, typename T>
void print(T t) {
  int i1 = 0, i2 = 0, i3 = 0;
  char c1 = '\0', c2 = '\0', c3 = '\0';
  using boost::tuples::tie;
  tie(i1, i2, i3, c1, c2, c3).get<num>() = t;                      //Error
in g++ & cl
  cout<<tie(i1, i2, i3, c1, c2, c3).get<num>()<<endl;  //Error in g++ & cl
}

int main() {
  print<0>(0);
  print<1>(1);
  print<2>(2);
  print<3>('a');
  print<4>('b');
  print<5>('c');
  return 0;
}
