bar holds std::vector of std::pair s of std::array s of foovalueadaptor s. foovalueadaptor implicitly converts int bool foovalue , makes little sense in contrived example, perfect sense in application. implemented convenience function bar::addentries adding multiple entries @ once, calling more 2 arguments fails compile using gcc 4.8.0. see error messages below. #include <array> #include <utility> #include <vector> enum class foovalue { a, b, c }; class foovalueadaptor { public: foovalueadaptor(bool value) : m_value(static_cast<foovalue>(value)) { } foovalueadaptor(int value) : m_value(static_cast<foovalue>(static_cast<bool>(value))) { } foovalueadaptor(foovalue value) : m_value(value) { } operator foovalue() { return m_value; } operator bool() { return m_value == foovalue::c; } private: foovalue m_value; }; template<std::size_t nfir...
