Here a complete code-example compiled with gcc 4.8.0 20121014 (experimental) using the compiler flags -Wall -std=c++11 -pedantic //--------------------- template<typename T> struct MemberGet{ static constexpr auto assign_operator = static_cast<T & (T::*)(const T &)>(&T::operator=); }; struct X {}; MemberGet<X> mg; //--------------------- "3|error: declaration of 'constexpr const auto MemberGet<X>::assign_operator' has no initializer|" I agree that this code should be accepted.
