// 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)) { ... }
