// BOOST_STATIC_CONSTANT workaround --------------------------------------- //

// statement that can never be reached.

// types in deduced contexts, e.g.
//
//     template <class T> void f(T, typename T::type);
//                                  ^^^^^^^^

// long long workaround ------------------------------------------//

// 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)) { ... }
