 // BOOST_[APPEND_]EXPLICIT_TEMPLATE_[NON_]TYPE macros --------------------------//

 //

 // Some compilers have problems with function templates whose

 // template parameters don't appear in the function parameter

 // list (basically they just link one instantiation of the

 // template in the final executable). These macros provide a

 // uniform way to cope with the problem with no effects on the

 // calling syntax.

 // Example:

 //

 //  #include <iostream>

 //  #include <ostream>

 //  #include <typeinfo>

 //

 //  template <int n>

 //  void f() { std::cout << n << ' '; }

 //

 //  template <typename T>

 //  void g() { std::cout << typeid(T).name() << ' '; }

 //

 //  int main() {

 //    f<1>();

 //    f<2>();

 //

 //    g<int>();

 //    g<double>();

 //  }

 //

 // With VC++ 6.0 the output is:

 //

 //   2 2 double double

 //

 // To fix it, write

 //

 //   template <int n>

 //   void f(BOOST_EXPLICIT_TEMPLATE_NON_TYPE(int, n)) { ... }

 //

 //   template <typename T>

 //   void g(BOOST_EXPLICIT_TEMPLATE_TYPE(T)) { ... }
