 using namespace lemon::concept;

 // Borrowed from boost:

 template <class T> inline void ignore_unused_variable_warning(const T&) { }

 int main()

 {

   //    This is the "right" way to check a concept:

   // boost::function_requires< BaseGraphItemConcept<BaseGraphItem> >();

   //    which is equivalent (considering compile-time checks) to

   // BaseGraphItemConcept<BaseGraphItem> bgic;

   // bgic.constraints();

   //    but not actually call or intatiates anything...

   //    It's doing aproximately this:

   typedef BaseGraphItemConcept<BaseGraphItem> CC;

   void (CC::*x)() = &CC::constraints;

   ignore_unused_variable_warning(x);

   //    But even more hackish...
