> I'm also not sure why you would replace moc with template magic - moc will generally not fail (or will tell you if, say, you forgot to inherit from QObject), whereas template errors are midæval latin on a good day. Liberal usage of static_assert can make your life much less painful. For the specific case you mentioned, static_assert(std::is_base_of<QObject, T>::value, "Type does not inherit from QObject") gives you a reasonable error message (unfortunately, there's no way to stringify a template argument in the error message (yet?), but your compiler should show you where the class is being instantiated)
