[Boost-users] [mpl::print] Making mpl::print<> function

I have the following which I expect to produce a compile time warning which includes the type name but it fails to do so. I found this in the C++ Template Metaprogramming book - but not in the MPL documentation. What am I missing here? Robert Ramey #include template<class T> int f(){ boost::mpl::print<T>; //static int x = g(); return x; } struct A { BOOST_STATIC_CONSTANT(bool, value = false); }; ... int x = f<A>();
