+// calling syntax.
+
+// Example:
+//
+// #include <iostream>
+// #include <ostream>
+// #include <typeinfo>
+//
+// template <int n>
+// void f() { std::cout << n << ' '; }

+// 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)) { ... }
