using namespace lemon::skeleton;

// 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...
